Question

heyyy !!
an engine pumps 800 kg of water through 10 metre in 8 second find the power of the engine if its efficiency is 75% please answer fast

Answer 1

Answer:

Mass(m)= 800kg

Height (h)= 10 m

Acceleration due to gravity (g)=10m/s^2

Time(t)=8s

Let the effective power be P,

$Power \: = \frac{m \times g \times h}{t}$

Power=(800×10×10)/8 watt

Power=10000 watt=10000×10^(-3) kW

Power=10 kW

Efficiency= 75%= 0.75

According to question,

0.75×P= 10kW

P×(3/4)=10 kW

P=40/3 kW
