Heat Transfer Operations
Heat Transfer Operations Interview
In a Heat Exchanger, heat cannot be transferred by all the three means, that is Conduction, Convection and Radiation simultaneously.
In which one of the following, Heat transfer takes place without any Conduction or Convection?
c) Cooling tower
d) Shell and Tube HE
How many Heat Exchangers can be classified on the basis of phase change of the fluids?
When we want to heat a stream of liquid by Steam, and the steam may condense into liquid. Then which of the following is best suited?
a) Steam on the side with the fins
b) Steam on the side with the fins and condensate drainage
c) Steam on the side with the fins and a brush to remove the condensate film from surface
d) Steam on the tube with the fins on inner surface of the tube passing through a pool of cooling liquid
Which one of the following relations are correct?
a) K1 < K2
b) K1 = K2
c) K1 > K2
d) K1 and K2 relation not defined
When we want to heat a stream of liquid by Steam, we usually keep removing the condensate from the surface of the tube.
What is Critical radius of insulation?
a) The maximum radius that can allow heat transfer
b) The maximum heat transfer coefficient at a maximum possible radius
c) The radius at which maximum heat transfer rate is observed
d) The minimum radius at which maximum heat transfer rate is observed
