Solving for area of section flow.

#### Inputs:

 hydraulic radius (Rh) 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 wetted perimeter (Pw) 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
