Question

A system undergoes three quasi -static
processes sequentially as indicated in the given
figure. 1-2 is an isobaric process, 2-3 is a
polytropic process with y = and 3-1 is a
process in which PV = constant.
P2 = P1 = 4 x 10 N/m²,
P3 = 1 x 10 N/m2 and Vi = 1m”. The
heat transfer for the cycle is AQ , the change in
internal energy is AU and the work done is
AW , then
PA
​

Answer 1

Answer:

A system undergoes three quasi -static

processes sequentially as indicated in the given

figure. 1-2 is an isobaric process, 2-3 is a

polytropic process with y = and 3-1 is a

process in which PV = constant.

P2 = P1 = 4 x 10 N/m²,

P3 = 1 x 10 N/m2 and Vi = 1m”. The

heat transfer for the cycle is AQ , the change in

internal energy is AU and the work done is

AW , then
