Heat Transfer Operations Practice Test 1

1. Which one of the following cannot be determined by knowing fouling factors?

2. Which of the following is not a subset of the category of Tubular Heat Exchangers?

3. What is Critical radius of insulation?

4. Which of the following is not a classification based on Construction of the heat Exchanger?

5. In which one of the following, Heat transfer takes place without any Conduction or Convection?

6. Which of the following statements are incorrect about Baffles in a Shell and Tube HE?

7. How can we graphically represent the temperature profile of a fluid flowing through a hot pipe with constant heat flux?
Tc = Temperature of the wall
Tb = Bulk Temperature

8. When we want to heat a stream of liquid by Steam, we usually keep steam on the shell side and fluid in the tube.

9. Plate type heat exchangers have less surface area as compared to a similar Shell and Tube heat exchanger. A Shell and Tube Heat Exchanger of equivalent area weigh six-seven times less than a Plate Type heat exchanger.

10. Velocity profile in a pipe is independent of axial position whereas Temperature Profile is not.
