The steam condenser in a thermal power plant is a heat exchanger of the type
direct contact
regenerator
recuperator
none of these
Answer
The normal automobile radiator is a heat exchanger of the type
parallel flow
counter flow
cross flow
Choose the correct statement with respect to a counter-flow heat exchanger
both the fluids at the inlet are in their coldest state
both the fluids at the exit are in their hottest state
both the fluids at the inlet are in their hottest state
one fluid is hottest and the other is coldest at inlet
The requirement of transfer of a large heat is usually met by
increase the length of the tube
decreasing the diameter of the tube
increase the number of tubes
having multiple tube or shell passes
The shell of a tubular heat exchanger is provided with expansion bellows to
facilitate an increase in the length of the boiler shell
impart structural strength to exchanger
account for the uneven expansion of shell and tube bundles
reduce the pressure drop
