Determine the final temperature (in ºC) in the cylinder. Determine the mass of the steam that has entered during this process. Determine the boundary work (in kJ) associated with the system during this process Determine the specific enthalpy (in kJ/kg) of the steam entering the cylinder.
An insulated, vertical piston–cylinder device initially contains 15 kg of water, 10 kg of which is in the vapor phase. Initially the pressure is 200 kPa inside the cylinder. A linear spring is connected to the piston therefore the pressure changes linearly with volume (P = m*v+b). Super heated steam at 0.5 MPa and constant temperature is allowed to enter the cylinder from a supply line until all the liquid in the cylinder has just vaporized and the pressure and volume in the cylinder have both doubled.
