U r my motivation i am from pakistan
Your explanation very well so thanku so much
Excellent Masha Allah bro ❤
Super duper sr ji 🙏
Good job
Thank you sir bhaut hi badiya explanation Kiya,thankyou❤❤
1st time Confusion clear...
Love you from Pakistan ❤❤❤
good informed video,thanks
I learn from u r video and share with my viewers
Excellent, the matter is feasible for my works up group
Zabardast sir .....
Good explain sir...
Very 👌👌. Thnx sir.
Superb❤
nice topic and good explain
😊

Sir please arrange a video the topic of sacrificial anode explain it
Hello Chandan Ji
Good video.... What is it's application in power plant?
Thanks.
Sir please softener plant ke bare me kuch batao
Plate tightening ka formula ka ek video bnayi sir or Ye corrugated plate ka angle heat transfer me kya role play krta hai is par ek video bnayi ye sir
Is it same as aluminium plate fin heat exchanger. Use in ASu. Or different?

Sir srcew compressor par video banaye please
Sure dear
Yes sir also about reciprocating compressor multistage.
Sir what is orifice???what is its function?
Sir how to find plate heat exchanger capacity
If both fluids are water and they mix up due to leakage inside, how will we know from outside that the water is mixing inside. Through pressure difference or temperature difference
Is it possible?
Plated heat exchanger ko kyun nahi repair Nahi kiya ja sakta hai

Plate type heat exchanger
Sir phe ka internal hole hoga ki naii haii
Internal hole ni rhta h,
Alternate plate me gasket ke design different hone se fluid different plate me flow krta h
@@PowerPlantDiscussion sir internal hole gas flow hoga ki water flow hoga ammonia plant me use hune wale p he And other refrigerant use hune wale phe me sir clear bataya sir
Piz reply sir
Generally water flow hota h, but different plant me alag ho skta h, depend krta h ki temperature kitna down krna h.
Thik haii sir OK thank u sir
Explain achha he lekin galat bata Rahe ho
