Thank you sir for this video. I am now an Engine Cadet and it helps me a lot.
You're welcome! Sorry for acknowledging too late. I hope it helped you. Goodluck on your career!
ang galing,, well explained ❤️❤️❤️
Maraming salamat sa magandang feedback! Mag uupload pa po ako in the near future! Sa ngayon gumagawa po ako ng app na para sa mga engineering seafarers. Sana po idownload nnyo once natapos na. Maraming salamat! 😇 keep safe!
Yung 0.000645 eh coefficient factor Ng fuel. May table Yan na depende sa density Ng @ 15 Ng supplied bunker. Makaluma na Yan. Yung accurate ngayun Yung astm table 54b
Can you check this formula: MT= V*WCF*VCF V: Obser volume at temperature (m3)---- WCF= Density at 15 C - 0.0011.---- VCF: taken from table 54......... All bunker surveyor use this formula for calculation..!!!!!!!!!
❤️❤️
Salamat sa malinaw na pagtuturo sir. More video
Thank you so much sa appreciation! I do hope marami kang natutunan! I am currently making an app for engineering seafarers. I hope i patronize ninyo once narelease na sa app store. Maraming salamat! 😇 thanks ulit sa napakagandang comment!
@@tropangmakinista7697 ay oo sir download namin agad yan. Wag sana kayo mag sawa na mag upload ng mga video tungkol sa pagbabarko lalo na sa makina
thank very much
You're welcome! Goodluck with your career!
New follower here sir..Well explained sir,malaking tulong to lalo na sa mga aspiring officer someday katulad ko makiniesta.maraming salamt.
Thank you so much :) sana ay marami kang natutunan sa video. Mag uupload pa ako ng iba pa. :) maraming salamat sa panonood :) keep safe!!
sir kilan kino consider ang WCF sa calculation kasi. Corrected volume x VCF x WCF = MT
WCF= SG at 15 deg - .0011
Nice sir..well explaine
Thanks for the compliment sir! I hope it helped you. Keep safe and God bless!
Good stuff

Sounding computation naman sir hehehe. Wag ka mag stop mag gawa ng vid
Thank you so much for your positive feedback. Sige sir, susubukan kong mag upload ulit ng bagong video. Nakafocus po kasi ako ngayon sa pag gawa ng app na para sa Engineering seafarers po para mas makatulong. Thank you so much and keep safe lagi sir!
Hi! Thanks sa info! :)
Constant po ba na ginagamit ang multiplier na 0.000645 sa kahit anung reading na Observe Temperature?
New subscriber here. Sir panu nmn po pag compute nung G.S.V. or Gross Standard Volume @15Deg.C😁slmat po
new subs mo sir., astig.
Thanks so much. New content probably next week :) medyo busy pa kasi i am making an app for seafarers. :) Thanks for watching! :)
sir may video ba kau paggawa ng bunker request
So far sir, di ko pa nagagawan ng video ito pero kasama ang topic na ito sa app na ginagawa ko intended para sa mga engineering seafarers. Mahaba habang proseso ito. Pero susubukan kong gumawa para maiupload ko dito. :)
deserve to subscribe this channel as i am engine cadet
Thank you so much for your positive feed back. :) I am currently developing an app for engineering seafarers. Hopefully you patronize it once I am finished developing it. Thank you and please keep safe!
May mobile apps kapo jan sir?
Kindly make this video in english language,too, for Non-tagalog people to understand. 🙏🙏🙏🙏
Will try to do so. I should have put an English subtitle on this one. Thank you so much for your support 😇 Keep safe!
Sir pwede ba about boiler naman ang gawan mo ng video..thanks
I cannot promise but I have the plans po. Sa ngayon busy po ako sa pagdevelop ng app for engineering seafarers po. Hopefully pag narelease napo i patronize niyo po. Maraming salamat! 😇
Example namn ng interpolation sir
Good day sir.. I am currently making an app that will help engineering seafarers. kaya po di ako nakakapag upload. Pero supposedly next release ko po sana ang interpolation topic. Thank you so much for your input sir and hopefully i can upload more in the near future. Thank you sir!!!
Sayo ko lang talaga Nakita Yung maayus na pag explain sir like bakit 15°c
Thank you so much sa napaka gandang compliment. Sana ay may natutunan ka sa video na ito. Keep safe!!!
Hello how to get this apps? I cant in playstore? Tnx
Hi! Havent lauched yet for years. There has been a problem sith the programming. Hopefully next year. Thanks for your support!
hello meron po... paano po magsolve ng consumption base po sa speed ng barko at distance travelled.
Normally, based on FO and RPM ang basehan ng pagcocompute ng consumption. Kasi ang pag compute ng konsumo ay base sa engine load ng barko.
Ang distance travelled ay nakabase sa ship speed. At ang ship's speed ay nakabase sa RPM ng barko. Ang load ay nacocompute gamit ang RPM.
Load = (Set RPM / RPM at MCR)^3 x MCR output
Sa madaling salita, base sa tanong mo, ang pagcocompute ng consumption ay nakabase parin sa RPM.
@@tropangmakinista7697 thanks po
@@tropangmakinista7697 pwd po ba nyo mtulungan sa problem q sir tungkol po sa fuel consumption.
@@edpaniagua2920 hanggat kaya nating sagutan. Pwede naman. :) maraming salamat! 😇
@@tropangmakinista7697 Slamat Sir.. paano q po kau ma message?
Given : Observed Temperature 25.5 Degree Celsius, Observed Density is 0.729 and Corresponding Density in 15 Degree Celsius is 0.7375. How is done it's VCF result is 0.00112 ? Please given me it's formula.
Hi! Thanks for your comment and as far as I could help, this is my answer to your question.
As based on the video I posted, the formula for VCF presented here is for approximation and must only be used if no available ASTM Table 54B.
As you saw from the video, the supposed formula is
1 - [ (Observed temp - 15) x 0.000645 ]
But since the density in concern is very low (lower than 0.85), the formula may be changed in to
Density at 15 deg C - [ (Observed temp - 15) x 0.0007 ]
So, using your given data,
0.7375 - [ (25.5 - 10) x 0.0007 ]
0.7375 - [ 10.5 x 0.0007 ]
0.7375 - 0.00735
Density at 25.5 deg C = 0.73015
So, the VCF used is
0.7375 - 0.73015 = 0.00735
VCF = 0.00735
I know there is a difference of
0.73015 - 0.729 = 0.00115
Which is very very small and can be considered as accurate enough.
I hope this helps. 😇 keep safe!
@@tropangmakinista7697 But I need accurate VCF=0.00112. But your result is 0.00115?
@@AlamgirHossain0110 Thank you for your comment. There might be a slight difference so it now depends on the engineer-in-charge's decision.
A difference of 0.00003 is very very small to even notice.
This is the closest formula I can give you. Thank you. 😇
@@tropangmakinista7697 please sent me your email, I want to sent the chart for accurate solution.
@@tropangmakinista7697Sir How do you get the Coefficient termal expansion of 0.0007 for the density of 0.729
san po nakikita ang 0.000645 sir. usually ung meru ndn iba gumagamit ng iba. merun .00065 merun dn 0.00067. medyu confusing lng. may table ba tay onbiard nyan
Sir thanks for your input. :)
Ang 0.000645 is actually derived constant through Calculus pag inobserve ang pattern ng pagchange ng volume ng bunker sa lahat ng temperatures. 0.00067 is normally used for diesel oil kasi mas mabilis mag expand ang D.O. compared sa bunker. 0.00065 is the rounded value for 0.000645. Regardless kung 645 or 65 ang gagamitin, may kokonting difference talaga compared sa actual na correction factor na makikita sa Table 54B Volume Correction Table for Petroleum. :)
Ang librong ito ay nasa onboard talaga at dito talaga mahahanap ang actual correction factor. Ginagamit lamang ang manual computation if ever na kelangang magcompute ng VCF na walang Table 54B na available. :)
I hope this helped po. Salamat at patuloy sana kayong manood sa ibang videos :)
@@tropangmakinista7697 thankz sir.godbless
@@rodpatac3259 No problem sir! Keep safe!! 😇
pano kaya yung mga unit measurements nyan sir.
Unlike sa schools sir and other professions, solving with the units is very important para hindi ka mawala sa process of solving. 😇 However, sa profession natin, we keep it simple as much as possible to avoid unnecessary mistakes and misunderstanding lalo na pag gumagamit ng units. Pero it is still possible sir to put the units during the solution pero I presented a direct no units solution para mas madali ifollow ang whole process. :)
But to give an example, katulad ng formula ng consumption:
1. (Present FM - Previous FM) ang unit na gamit dito is liters.
2. Next step is divide it by 1000 because there are 1000 liters in 1 MT.
3. Times sa SG and VCF na walang units, in the end, MT ang makukuha mong unit.
I forgot to specify or indicate na ang formulas presented are in metric system. :)
Thanks for you input sir and I hope you learned something from the video 😇
Keep safe!
@@tropangmakinista7697 thank you po sa sagot sir. i appreciate it. aspiring 3rd engineer po kasi ako nagaaral pa hindi pa nakaacto baka kasi tatanongin ng hepe balang araw. at least may maisagot hehe. anyways Godbless sayo sir nag subscribe na rin ako.
quality mga videos mo sir keep it up!
@@MrSHAWNANINO I am currently making a new video about Noon Report Computation at concepts na dapat tandaan kung bakit kinokompyut ito. And I am currently developing an app for aspiring Marine Engineers so plesse look forward to hopefully watch and download them. I am very glad I helped. Please recommend this low key channel to your friends. Thank you for your support! 😇
@@tropangmakinista7697 THANK YOU SO MUCH SIR MALAKING TULONG PO YAN!!
panu nakuha ang 0.000645?
Goodmorning mam :) constant po yan sa correction ng temperature correction :) ang iba naman ginagamit 0.0007 pero mas maganda ang kuha pag 645 :)
Kindly explain this in English. Your audience aren't only filipino
background is very irritating, in your voice.
Thank you so much for your feedback. I'd do better in my next videos. 😇 please keep safe and God bless! 😇
