Question

a water pump prices 50 litres of water through a height of 25 metre in 5 second calculate the power was the pump suppliers take Gravity 10 kilogram and density of water 1000 M cube

Answer 1

may be it is 2000liters

Answer 2

Height = 25m

Time = 5s

Volume = 50l

${ \pink{ \bf{ Let's \: convert \: volume \:to \:density: }}}$

density = mass / volume

So,

${ \pink{ \bf{ 1m² = 1000l }}}$

${ \pink{ \bf{ density = mass / volume }}}$

1000=mass/(1/1000×50)

mass=1000×50×1/1000

${ \pink{ \bf{ =50kg }}}$

${ \pink{ \bf{W=F=mg=50×10=500 }}}$

P=500×25/5

${ \pink{ \bf{P=2500W \: Ans }}}$
