Fruit juice at 20 degrees Celsius contains 5% total solids concentrated via a single effect evaporator. The evaporator is operated in a vacuum at an evaporation temperature of 80 degrees Celsius and 85% quality steam is supplied at 169.06 KPA. The desired concentration of the final product is 40% total solids. the rate of concentrated product leaving the evaporator is 2500 kg / hour. the specific heat of the fruit juice is 4.05 kj / (kg degrees Celsius) and the concentrated product is 3.175 kj / (kg degrees Celsius). Calculate a. The required steam rate is b. the steam economy of the steam economy. If the condensate temperature is released at 90 degrees Celsius
