Please describe in detail the process of obtaining the final pressure

3.16 A rigid tank contains 2.27kg of a two-phase, liquid-vapor mixture of H2O, initially at 127C with a quality of 0.6 . Heat transfer to the contents of the tank occurs until the temperature is 160C. Show the process on a pv diagram. Determine the mass of vapor, in kg, initially present in the tank and the final pressure, in kPa
