Net work of the cycle and the heat transfer

Assignment Help Mechanical Engineering

Reference no: EM13717241

A system consisting of 1kg of H2O undergoes a cycle composed of the following closed processes:

Process 1-2: Isochoric heating from P1 = 5 bars, T1 = 160ºC to P2 = 10bars

Process 2-3: Isobaric cooling until a saturated vapor

Process 3-4: Isochoric cooling

Process 4-1: Isothermal expansion with Q4-1 = 815.8 kJ

Sketch the cycle on T-v and P-v diagrams and clearly label your sates. Neglecting kinetic and potential energy effects, determine the net work of the cycle and the heat transfer for each process, all in kilojoules
