A raw juice is subject to flash distillation. The juice is
heated in a heat exchanger and then flashes in a vacuum vessel.
There is no phase change in heat exchanger. If heat at a rate of
270,000 kJ/h is transferred to the heat exchanger. The
following data are given: flow rate and temperature of the solution
at the inlet of the heat exchanger is 1000 kg/h and 50oC, specific
heat capacity of the solution is 3.8 kJ/kg oC, and the absolute
pressure in the vacuum vessel is 70.14 KPa.
Find:
a). The temperature of the juice at the exit of the heat
exchanger
b). The amount of overhead/flashed vapor and finished juice
leaving the vacuum vessel
heated in a heat exchanger and then flashes in a vacuum vessel.
