RPM to Watts Formula:
| From: | To: |
The RPM to Watts formula calculates mechanical power from torque and rotational speed. It's commonly used in engineering applications to determine the power output or requirement of rotating machinery.
The calculator uses the formula:
Where:
Explanation: The formula converts rotational motion parameters (torque and RPM) into mechanical power output. The π/30 factor converts RPM to radians per second.
Details: Accurate power calculation is essential for designing mechanical systems, selecting appropriate motors, evaluating energy efficiency, and ensuring proper sizing of mechanical components.
Tips: Enter torque in newton-meters and RPM in revolutions per minute. Both values must be positive numbers. The calculator will compute the corresponding power in watts.
Q1: What's the difference between mechanical power and electrical power?
A: Mechanical power refers to the rate of doing work in mechanical systems, while electrical power refers to the rate of electrical energy transfer. They're related but measured differently.
Q2: Can this formula be used for any rotating system?
A: Yes, this formula applies to any rotating mechanical system where torque and RPM are known, including engines, motors, turbines, and pumps.
Q3: Why is torque measured in newton-meters?
A: Newton-meters is the SI unit for torque, representing the rotational force applied at a distance of one meter from the pivot point.
Q4: How does RPM affect power output?
A: Power is directly proportional to both torque and RPM. Doubling either parameter (while keeping the other constant) doubles the power output.
Q5: What are typical power values for common applications?
A: Small motors might produce 100-1000W, car engines typically produce 50-300kW, while industrial turbines can produce megawatts of power.
