A0.1 mole% caustic soda (naoh) solution is to be concentrated in a continuous evaporator. the solution enters the unit at 25°c at a rate of 150 mol/min and is concentrated to 5 mole% at 60°c. hot dry air at 200°c and 1.1 bar absolute is bubbled through the evaporator and leaves saturated with water at 60°c and 1 atm. calculate the required volumetric flow rate of the entering air and the rate at which heat must be transferred to or from the unit. assume that the heat capacity per unit mass of all liquid solutions is that of pure water

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
