Question

A cylinder-piston equipped with a set of stops for the piston is initially filled with saturated liquid-vapor mixture of water at P = 170 kPa. Heat is transferred to the water until the volume increases by 25%.

Determine:

a) The initial and final temperature,

b) The mass of the liquid when the piston starts moving,

c) The work done during the process

d) Show the process on a P-v diagram

Answer 1

by using steam table of water we can find corresponding saturation temperature of the liquid vapor of water

after heating the mixture more liquid will be converted into vapor and piston starts moving whenl all of the liquid has been converted into vapor

during this time pressure will remain constant
