ASSIGNMENT ON MASS AND ENERGY BALANCE ANALYSIS 1. A tomato-juice evaporator takes in juice at the rate of 1200kgh1. If the concentrated juice contains 35% of solids and the hourly rate of removal of water is 960kg, calculate: a) The percentage (\%) of water in the original juice and b) The quantity of steam needed per hour for heating if the evaporator works at a pressure of 10kPa and the heat available from the steam is 2,200 kJkg1. Assume no heat losses
