Axial flow Compressor 2

[@MotivesMedia]

Why did I choose engineering? 😭

[@johnkimina8363]

I think while substituting to the work done to the air one shouldn't substitute the temperature T'but the isetropic temperature rise because T' it includes temperature added due to losses

[@yahitajam7944]

We are finding actual direction of air, so using actual temperature at exit is more important than isentropic temperature at exit.

[@VEERSINGH-bu2zi]

Since no stagnation data given then why taking stagnation properties...can we use static temp. and pressure instead of stagnation

[@sunilmohodmh31]

If nothing is mentioned then treat as stagnation condition

[@VEERSINGH-bu2zi]

@@sunilmohodmh31 ok sir..
And one more doubt regarding centrifugal compressor is that if it is delivering 600cubicmetre per minute free air. And mentioned air is compressed from 1bar , 20degree Celsius. Then static temp. will be 15degree and stagnation 20degree because mentioned free air.

[@kgireeshreddy6171]

Where is the direction of air entry?

[@yahitajam7944]

Also power will be 190.8 Watt not KW, if units are calculated properly. Correct me if am wrong

[@Vikram21-2K]

U r right cp = 1005 j/kgK

[@yahitajam7944]

Sir total work done unit is taken as kJ/kg or KJ/s ?

[@behappy5229]

why u not take the vlaue of mass for forming the equ. 1st

[@sunilmohodmh31]

for specific work, we do not require mass

[@johnkimina8363]

I think its because the mass cancels out at both sides
