butane by weight. This mixture is compressed from 100 kPa and 20ºC to 1000 kPa in a

reversible, isothermal, steady-flow compressor. Determine the work and heat transfer

for this compression per unit mass of the mixture.

hi there... i just cant figure out where to start... perhaps... should be using few of these equations : -

W in = q out + (h2 - h1)

Win = Q out

since it's isothermal, T1 = T2, change of KE and PE will be negligible

steady flow , mass flow rate will be constant

i just.. blurred.... i hope there's enlightment.... i need to submit this on coming friday.

thank you

For that, you'd need to figure out how pressure varies with the volume of a unit mass -- say 1 kg -- along the path described.
