Steam is leaving a 4-L pressure cooker whose operating pressure is 150 kPa. It observed that the amount of liquid in the cooker has decreased by 0.6 L in 40 min after the steady operating conditions are established, and the cross-sectional area of the exit opening is 8mm2. Determine
a)The mass flow rate of the steam and the exit velocity
b)The total and flow energies of the steam per unit mass
c)The rate at which energy leaves the cooker by steam.
