Answer #1

B) Internal energy is not related to efficiency.

Because, The efficiency of a particular pump is
estimated by determining two values. These
values are pump flow rate and total head.

Flow rate is the total water volume that
passes through a fixed point over time. Flow
rate can be measured using a flow meter.

Total head is determined by measuring
the distance from the source water surface
to the output of the pump, as well as the
pressure the pump is producing at the
pump outlet.
