Q1: Steam side heat transfer co-efficient in an evaporator is in the range of __________ kcal/hr.m²°C.

ANS:D - 5000-15000

The steam side heat transfer coefficient in an evaporator typically falls in the range of 1000-1500 kcal/hr.m²°C. This range represents the typical values encountered in industrial evaporators where steam is used as the heating medium. The heat transfer coefficient depends on various factors such as the design of the evaporator, the properties of the steam, and the operating conditions. Generally, higher values are desirable as they indicate more efficient heat transfer from the steam to the liquid being evaporated.
