Question

An evaporator with an area of ​​83.6 m2 and U = 2638 kcal / h m2 C is used to obtain distilled water to be fed into a boiler. Water from the pipe network containing 400 ppm of solids dissolved at 15 C is introduced into the evaporator. The evaporator operates under a pressure of 1 atm. For heating, saturated steam is available at 1.7 atm absolute.
