An open tank containing acetone at 20 oC is being pumped out through a 2 in inner diameter pipe and into a 1-in nozzle. The tank level is 4.5 ft above the pump. Calculate the pump power requirement to achieve a flow rate of 0.2 ft3/s. Assume a 45% pump efficiency

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
