In the rule q= U A (T1-T2), U stands for ...............

• Rate of Heat Transfer

• Overall Heat Transfer Coefficient

• Area

• Temperature Difference

All of the following are disadvantages of the Evaporating Pan except ...............

• Having only natural circulation

• Give rise to foam when boiled

• Used for evaporation of aqueous liquids only

• 1. Simple and cheap to construct

Evaporating still can be used for thermolabile materials

• Yes

• No

....................... Evaporator requires low head room and is easy to install

In the short vertical tube evaporator, the use of a tubular ......................... increases the heating area largely

.................................. is the device where the heating source of an effect is the vapor originating from the preceding evaporation effect
