The formula used to determine power is?

The formula used to determine power is derived from the relationship between work done and the time taken to do that work. In physics, power is defined as the rate at which work is performed or energy is converted. Therefore, when you take the amount of work done and divide it by the time taken to do that work, you obtain the measure of power. This is expressed by the formula:

Power = Work / Time

This formula indicates how much work is done in a specific time interval, allowing for the quantification of power in units such as watts (where 1 watt equals 1 joule per second). Understanding this relationship is important in water and fuel systems maintenance, as it helps in calculating the efficiency of pumps and engines based on their work output.

The other formulas provided do not represent the concept of power. For example, work multiplied by time does not relate to power, nor do distance divided or multiplied by time. Understanding the correct relationship is essential for calculations in various engineering and maintenance scenarios.
