A pump of power 20 kW is used to jump out the water from a well 12 m deep . Calculate the efficiency of the pump if 5,000 kg of water is pumped out in 1 minute .

Explanation

To calculate the efficiency of the pump, we will follow these steps:

### Step 1: Calculate the work done by the pump
The work done (W) by the pump to lift the water can be calculated using the formula:
\[ W = m \cdot g \cdot h \]
where:
