an electric water pump raises 500 kg of water through a vertical height of 25 m in 50 sec. Calculate the power of electric pump. Take g=10N/kg

To calculate the power of an electric water pump, we need to use the formula:

Power = Work / Time

First, let's calculate the work done by the electric water pump. The work done is equal to the force exerted by the pump multiplied by the distance it lifts the water:

Work = Force × Distance

The force exerted by the pump is equal to the weight of the water being lifted. The weight can be calculated using the formula:

Weight = Mass × gravitational acceleration (g)

Given that the mass of the water being lifted is 500 kg and the gravitational acceleration is 10 N/kg, we can find the weight of the water:

Weight = 500 kg × 10 N/kg = 5000 N

Now we can calculate the work done:

Work = Weight × Distance
= 5000 N × 25 m
= 125,000 N·m (or Joules)

Next, we can calculate the power by dividing the work by the time taken:

Power = Work / Time
= 125,000 N·m / 50 s
= 2500 Watts

Therefore, the power of the electric water pump is 2500 Watts.

P = F * d/s = Mg * d/t = 5000 * 25/50 =

2500 J./s = 2500 W.
