### Solving for pipe diameter.

#### Inputs:

 friction factor (f) head loss (h) 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 pipe length (L) 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 flow velocity (V) meter/second centimeter/hour centimeter/second foot/day foot/second inch/hour inch/second kilometer/hour kilometer/second knot mach sea level 15 C meter/day mile/hour mile/second millimeter/second speed of light in vacuum yard/second acceleration of gravity (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

#### Conversions:

 friction factor (f) = 0 = 0 head loss (h) = 0 = 0 foot pipe length (L) = 0 = 0 foot flow velocity (V) = 0 = 0 foot/second acceleration of gravity (g) = 0 = 0 foot/second^2

#### Solution:

 pipe diameter (D) = HAS NOT BEEN CALCULATED
