3- A gas undergoes a thermodynamic cycle consisting of the following process:
Process 1-2 isothermal expansion from condition 1 to V 2 =
0.103 rrr', P2
=
1.4 bar
and W1•2
=
18.8
kJ.
Process 2-3 constant pressure proe�_s�
Process 3-1 constant volume process with U1 - U3 =
26.4 kJ.
Neglect the change in kinetic energy and potenial energy.
a) Sketch the cycle on P-V diagram.
·
b) C�lculate the net work 'done for _each process and for the cycle�
c)'Calculat�'#ie heattransfer for each process
