Pump power (unit: watts) is a key parameter for measuring its efficiency. The calculation formula is: Power = Flow rate (m³/s) × 9.8 m/s² × Lifting height (m). For example, to lift 1 m³/s of water to a height of 10 meters, the theoretical power required is 98 kW. This parameter directly impacts energy consumption control in engineering scenarios. For example, when designing agricultural irrigation systems or selecting fire pumps, it's crucial to match actual head and flow requirements.
