Question

I kW motor-pump, pumps out water from a well 10 m deep. Calculate the mass of water pumped out per second. (Use g = 10 m/s).

Answer 1

I got the answer as 10 kg per second using the formula
\[m=\frac{ Pt }{ gh }\]

Is it correct??

would appreciate if someone could explain with full solution....

Answer 2

Yes, it is.
Notice that the unit is kg/s.
So the formula you use would be
\[\frac{m}{t}=\frac{P}{gh}\]

Answer 3

Okay noted. Thanks !!!
