Calculating Pump Efficiency

How do you calculate the efficiency of a pump operating?

Given data: Pump discharge 500L/s at the height of 25m, Drive motor delivers 100Kw of power to the pump.

Efficiency Calculation:

The efficiency of the pump, which is the ratio of work done by the pump to the power supplied, is calculated to be exceeding 100%, indicating some error in the input data as efficiency cannot exceed 100%.

To calculate the efficiency of a pump operating, we need to compare the actual work done by the pump to the power supplied to it. In this case, the pump is lifting water to a height of 25m with a discharge rate of 500L/s, while the drive motor is delivering 100Kw of power to the pump.

The efficiency of the pump can be calculated using the formula: Efficiency = (Work Done / Power Supplied) * 100%. This ratio should ideally be less than or equal to 100%.

However, in the given data, the efficiency is calculated to be exceeding 100%, which indicates an error in the input data. This could be due to inaccuracies in the measurements or calculations provided.

To correct this, it is essential to double-check the data and calculations to ensure accuracy and make necessary adjustments if needed. Efficiency exceeding 100% in this scenario is not physically possible and indicates a mistake in the calculation process.

Therefore, it is crucial to thoroughly review and verify the data to determine the accurate efficiency of the pump operating under the given conditions.
