Inside a boiler with a volume of 0.5 m, there is wet steam with a half volume of water at 140 kPa pressure. As a result of giving heat at constant pressure, after half of the water is vaporized, heat is continued until the pressure in constant volume is 1 MPa. Then, after giving heat at constant pressure, according to the temperature is 400 ° C; Show the temperature, pressure, volume, internal energy, enthalpy and dryness levels in a table during state changes.
b) Show the state changes in P-v and T-v diagram.
c) Find the work and heat transition after the state changes.
d) Find the required amount of fuel (natural gas, coal, fuel oil)
for the heat given after the state changes by making the necessary
assumptions.
