2. Diethyl ether ( SG=0.71, viscosity: 0.224cp ), 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 450mmHg. Flow rate of the diethyl ether is 120kg/min. Losses in the pipe between the condenser and the pump can be estimated as 15J/kg
