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

Respuesta :

Answer:b

Explanation:

We know power delivered by Pump is

[tex]P=\rho \times Q\times g\times \Delta H[/tex]

where [tex]P\rho [/tex]=Density of fluid

[tex]Q[/tex]=Flow rate

[tex]g[/tex]=acceleration due to gravity

[tex]\Delta H[/tex]=Change in Elevation

If [tex]\Delta H[/tex] is increased by 4 time then

[tex]P'=\rho \times Q\times g\times (4\Delta H)[/tex]

[tex]P'=4 P[/tex]

So power increases by four times.
