Question
Calculate power if a pump which can lift 400kg of water through a height of 10m in 20secs?
Solution
Sure, to calculate the power, we need to use the formula for power which is work done divided by time taken.
Step 1: Calculate the work done Work done is given by the formula: Work = mass * gravity * height Given: Mass (m) = 400kg Gravity (g) = 9.8 m/s^2 (approx) Height (h) = 10m
So, Work = 400kg * 9.8 m/s^2 * 10m = 39200 Joules
Step 2: Calculate the power Power is given by the formula: Power = Work / time Given: Work = 39200 Joules Time (t) = 20s
So, Power = 39200 Joules / 20s = 1960 Watts
Therefore, the power of the pump is 1960 Watts.
