Calculations Regarding a Piston-Cylinder Device
Not what you're looking for?
A piston-cylinder device contains 5kg of steam at 100kPa, quality of 50%. This steam undergoes two processes as follows: (Process1-2) Heat is transferred to the steam in a reversible manner while the pressure is held constant until the steam exits as a saturated vapor. (Process 2-3) The steam is compressed in an adiabatic, reversible process until the pressure is 500kPa.
(a) Sketch these processes with respect to the saturation lines on a single T-s diagram.
(b) Determine the heat added to the steam in the entire process 1-3, in kJ.
(c) Determine the net work done by the steam in the entire process 1-3, in kJ.
(It's a reversible adiabatic process, this is not a cycle)
