Polytropic process Example Problems

O In a reversible compression, 1 mol of an ideal gas in a piston cylinder device undergoes a pressure increase from 1 bar to P. Temperature increases from 500K to 1000K. Compression path is PVA1.5- constant. Heat Capacity is Find final pressure

State State 2: P ba, lOOOK bar,Sook P V 1 . S Also, PV=nRT =const. V= nRT 1- S T' = cons t ant . 12

1.S O S 2. 2 2.

What is work required for the polytropic process? n-i n- 8.314

Calculate the Heat Transferred in this procesS 3136-8.314 = 2.3.ous x SOD = 11 S23 31

why did u take the average temp for calculation of Cp ?

We can also calculated the Heat transferred in this process by using the equation dq = nCp dT and integrate this eqn from 500K to 1000K. What''s wrong in this method.

Yes. I have the same doubt.

dQ is not equal to Cp dT as it is not a constant pressure process

However why don't we calculate delta U by integrating Cv dT as heat capacity is not constant and function of temperature ?
