A. Calculate the evaporation rate from a water body surface using the energy balance method, if the net radiation of 300 W/m^2 and the air temperature of 23°C. Assume no sensible heat or ground heat flux.
b. Calculate the evaporation rate of the system in part a. if the sensible heat flux is 0.5 W/m^2 and ground heat flux is 1.45 W/m^2.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
