A pump is used to transport water from a reservoir at one elevation to another reservoir at a higher elevation. If the elevation difference increases by four times, the pump power required:

A) Increases by two times

B) Increases by four times

C) Increases by eight times

D) Increases by sixteen times

b

Explanation:

We know power delivered by Pump is

where =Density of fluid

=Flow rate

=acceleration due to gravity

=Change in Elevation

If is increased by 4 time then

So power increases by four times.

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.
