Question

motor pump can it lift 5000 litre of water to a vertical height of 15 m in 5 minutes calculate the work done by motor pump and its power density of water 1000 kg metre cube is is equal to 9.8 metre per second square​

Answer 1

plz rate my answer brainliest one

Explanation:

Here we have the volume of water as 50/1000 m  

3

 after converting we get this.We know that mass=density×volume

M=1000×50/1000=50kg.

Force is equal to m×g = 50×10 =500N

Workdone=F×s=500×25=12500J

Power=work/time=12500/5=2500Watt.

Hence,power generated is 2500 W
