#### Inputs:

 flow rate (Q) meter^3/second cc/hour centimeter^3/second centimeter^3/hour deciliter/minute foot^3/minute foot^3/second gallon/minute liter/day liter/minute liter/second meter^3/day meter^3/minute milliliter/hour milliliter/minute discharge coefficient (Cd) orifice area (AO meter^2 acre international acre US survey are barn centimeter^2 foot^2 hectare inch^2 kilometer^2 mile^2 mile^2 nautical ping township yard^2 gravitational constant (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:

 flow rate (Q) = 0 = 0 meter^3/second discharge coefficient (Cd) = 0 = 0 orifice area (AO = 0 = 0 meter^2 gravitational constant (g) = 0 = 0 meter/second^2

#### Solution:

 center line head (H) = HAS NOT BEEN CALCULATED
