SUMMARY

The discussion focuses on calculating torque produced by a steam-powered turbine to run a compressor. Key figures used in the calculation include RPM, the combined weight of the turbine blade and shaft, and the radius of the turbine blade. The basic formula for torque is established as the power produced by the turbine divided by the angular velocity of the rotor. This method provides a straightforward approach to determining the torque necessary for compressor selection.

PREREQUISITES
  • Understanding of basic physics principles, specifically torque and power calculations.
  • Familiarity with RPM measurement using a tachometer.
  • Knowledge of the relationship between angular velocity and torque.
  • Basic engineering concepts related to turbine design and operation.
NEXT STEPS
  • Research the formula for calculating torque: Torque = Power / Angular Velocity.
  • Learn about the role of RPM in determining angular velocity in rotational systems.
  • Explore methods for measuring power output from steam turbines.
  • Investigate the impact of blade radius on torque and overall turbine efficiency.
USEFUL FOR

Mechanical engineers, turbine designers, and anyone involved in the design and operation of steam-powered systems seeking to understand torque calculations for effective compressor selection.

I have designed and built a steam powered turbine that I am trying to get to run a compressor. In order to choose a compressor I've been trying to calculate how much torque my turbine is producing. The only figures i have are...

RPM - found using a tachometer
Combined weight of turbine blade and shaft
Radius of turbine blade

Is there anyway to calculate the torque using these figures?

In a basic way you can take the power produced by the turbine and divide by the angular velocity of the rotor.
