Question

Determine the correctness or otherwise of the following Assertion [a] and the Reason [r].

Assertion [a]: Condenser is an essential equipment in a steam power plant.

Reason [r]: For the same mass flow rate and the same pressure rise, a water pump requires substantially less power than a steam compressor.

1. Both [a] and [r] are true and [r] is the correct reason for [a].
2. Both [a] and [r] are true but [r] is NOT the correct reason for [a].
3. [a] is true but [r] is false
4. [a] is false and [r] is true.

Answer 1

Correct Answer - Option 2 : Both [a] and [r] are true but [r] is NOT the correct reason for [a].

Condenser is an essential equipment in a steam turbine because it is not economical to feed steam directly to the boiler.

For same mass flow rate and the same pressure rise, a water pump require very less power because the specific volume of liquid is very less as compound to specific volume of vapour.
