Hhay Mkhulu this is what I wanted for my test thank you I now have clear understanding. Only if there was a way to post questions here from our problems to be solved, it would have been great.
No... You can't use it..... Because currently used psychometric chart is for air at 1 atm pressure.... You can't use it to evaluate air properties at an elevated altitude due to pressure less than 1 atm
Thank you, well explained!
Nice work thanks
That was very helpful ,thanks mchana

Thank you for such a good class, just to clarify, does psycometric chart used at the video, calculated for 4300m of altitude?
No, such charts are printed for sea level usually.. For higher altitudes one has to use math equations.

nice explanation
thankyou !!
the solving of m4 is wrong... The expretion would be m3-m1(w2-w1)
m3-m4=ma(w2-w1) therefore
m4=m3-ma(w2-w1)
m3-ma(w2-w1) is equivalent to m3+ma(w1-w2)
