Power Transmission Calculator vs Fan Airflow and Power Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Power Transmission Calculator
Converts torque (N·m) and rotational speed (rpm) into mechanical power in kilowatts. Use it when sizing motors, drives, or shafts, or when checking whether a drivetrain can handle a given load without overheating.
- Answers
- Power (kW)
- Inputs
- Torque, Rotational Speed
Fan Airflow and Power Calculator
Calculates fan power consumption from blade swept area, rotational speed, and static pressure. Use it when sizing ventilation fans or verifying energy budgets for HVAC and industrial systems.
- Answers
- Airflow Rate (m³/h)
- Inputs
- Fan Diameter, Rotational Speed, Static Pressure
