The Power Input Calculator computes the energy required to drive a pump, essential for numerous applications across industries. It assists in evaluating the power necessary for fluid transportation, considering factors such as flow rate, total head, density of the slurry, acceleration due to gravity, and pump efficiency.
Formula of Power Input Calculator
The formula for the Power Input (Pin) Calculator is expressed as:
Pin = (Q * H * ρ * g) / η
Where:
- Pin stands for the pump input power in watts, horsepower, or related units.
- Q represents the flow rate, often measured in cubic meters per second or liters per second.
- H signifies the total head, typically measured in meters or feet.
- ρ denotes the density of the slurry in kilograms per cubic meter or pounds per cubic foot.
- g represents the acceleration due to gravity, measured in meters per second squared or feet per second squared.
- η symbolizes the pump efficiency in decimal form.
Table of General Terms:
| Term | Measurement |
|---|---|
| Flow Rate | Cubic meters per second (m³/s), Liters per second (L/s) |
| Total Head | Meters (m), Feet (ft) |
| Density of Slurry | Kilograms per cubic meter (kg/m³), Pounds per cubic foot (lb/ft³) |
| Acceleration due to Gravity | Meters per second squared (m/s²), Feet per second squared (ft/s²) |
| Pump Efficiency | Decimal value (0-1) |
Example of Power Input Calculator
Consider a scenario where a pump operates with a flow rate of 10 liters per second, a total head of 15 meters, a slurry density of 1000 kilograms per cubic meter, an acceleration due to gravity of 9.81 meters per second squared, and an efficiency of 0.85. Plugging these values into the formula, we can determine the power input required for this setup.
