# Trommel Screen Design Calculator

## Water and Wastewater Treatment Material Separation and Recovery

Solving for critical speed.

#### Inputs:

 gravitational acceleration (g) meter/second^2 centimeter/second^2 foot/second^2 inch/second^2 kilometer/second^2 mile/second^2 millimeter/second^2 yard/second^2 drum radius (r) meter attometer centimeter chain dekameter decimeter exameter femtometer foot gigameter hectometer inch kilometer light year link megameter micrometer micron mile millimeter nanometer petameter picometer rod terameter yard

 |

#### Conversions:

 gravitational acceleration (g) = 0 = 0 centimeter/second^2 drum radius (r) = 0 = 0 centimeter

#### Solution:

 critical speed (ηc) = HAS NOT BEEN CALCULATED
