Watt (W) in aircraft design refers to the SI unit of power, specifically the rate at which energy is transferred or converted. In aviation, the watt is used to quantify various aspects related to power, including engine power output, electrical power generation and consumption, and the power required for aircraft systems. The formula for watt and its SI unit are as follows:
Watt Formula: The formula for calculating power (P) in watts (W) is based on the rate of energy transfer or conversion:
- P: Power, measured in watts (W).
- E: Energy, measured in joules (J).
- t: Time, measured in seconds (s).
