A single‐effect evaporator concentrates 7,000 kg/h of a solution containing 10 wt% NaOH and 1.5 wt% sand entering at 40 ºC to a final concentration of 50 wt% NaOH. The pressure of saturated steam used is 198.5 kPa and the pressure in the vapor space of the evaporator is 12.35 kPa. The overall heat transfer coefficient is 1700 W/m2.K. Calculate the steam used. Assume that the sand is passing through, i.e., it is not building up in the system. Ignore any effect the sand may have...
