A pump on the ground floor of a building can pump of water to fill a tank of volume `30 ms^(3)` in `15 min`. If the tank is `40m` above the ground and the efficiency of the pump is `30 %` , how much electric power is consumed by the pump? `("Take" g = 10 ms^(2))`

Explanation

To solve the problem, we need to calculate the electric power consumed by the pump. We will follow these steps:

### Step 1: Calculate the mass of water
The mass of water can be calculated using the formula:
\[ \text{mass} = \text{density} \times \text{volume} \]

Given:
- Density of water, \( \rho = 1000 \, \text{kg/m}^3 \)
