4. Diethyl ether (SG=0.71, viscosity: 0.224 cp), which is the product from a distillation process, is being condensed in a tank shown in the figure and pumped away as liquid. The total pressure in the condenser is equal to the vapor pressure of diethyl ether which is 450 mmHg. Flow rate of the diethyl ether is 120 kg/min. Losses in the pipe between the condenser and the pump can be estimated as 15 J/kg. Vapor Condenser P=450 mmHg Cooling Water ho=? (a) If the net positive suction head of the pump is 3 m of liquid, what must be the least height of the liquid level in the condenser above the pump inlet?
