A 35 wt.% ammonia solution at 97 PSIA is fed at a rate of 120 lbm/h to an ultra-fast evaporator unit in which the pressure is at a rate of 120 lbm/h to an ultra-fast evaporator equipment in which the pressure is 17 PSIA. The enthalpy of the feed solution in relation to the reference conditions used to construct the The enthalpy of the feed solution relative to the reference conditions used to construct the ammonia enthalpy-concentration diagram is 100Btu/lbm. The vapor composition is expected to be is expected to be 85% by weight of ammonia.

Determine: the temperature of the stream exiting the evaporator determine: the temperature of the stream leaving the evaporator, the mass fraction of ammonia in the liquid product, the flow velocities of the product flow velocities of the liquid and vapor product streams, and the rate at which heat is transferred to the vapor. at which heat is transferred to the vaporizer.
