1. Sketch the cycle

2. Determine Q cycle and Q31

This is a gas compression question

An inert gas held in a plunger undergoes three stages:
Stage 1-2: the gas is compressed without any heat transfer
where the initial conditions are 11m³ and 2kPa and final
conditions 3m3 and 8kPa and PV is a constant
Stage 2-3: the gas undergoes expansion where 287kJ is
added and v2 returns to 11m3 at constant pressure of 8kPa
Stage 3-1: the plunger is stationary as the gas cools and
returns to its initial state
