A cylinder-piston device provided with stops, so that the water supports the weight of the piston, and the force of the atmosphere,It contains water, initially at 300 kPa and 0.5 m3 / kg. The water is heated to a saturated steam condition and the plunger rests on the stops. With the plunger on the stops, the water is heated up to the pressure of 600 kPa. In the P-V and T-V diagrams, with respect to the saturation lines, the process curves go through the initial and final states of the water. On both T-V and P-V diagrams draw the isotherms that pass through both states, and show their values in ° C, in the isotherms. (see img 1)

An expansion valve is a part of an adiabatic rigid steam boiler. Steam's initial pressure and temperature are set to 1 MPa and 350°C. In a matter of seconds, the tank's expansion valve was opened, causing it to fill to capacity. Calculate the pressure in the expansion valve if the steam flowing through it has a temperature of 300C.
