#### Conversions:

 static head or elevation (Z1) = 0 = 0 meter static head or elevation (Z2) = 0 = 0 meter pressure (P1) = 0 = 0 pascal pressure (P2) = 0 = 0 pascal velocity (V2) = 0 = 0 meter/second density (p) = 0 = 0 kilogram/meter^3 acceleration of gravity (g) = 0 = 0 meter/second^2 head loss (h) = 0 = 0 meter

#### Solution:

 velocity (V1) = HAS NOT BEEN CALCULATED

Select an equation to solve for a different unknown
 Solve for head loss Solve for static head or elevation at point 1 Solve for pressure at point 1 Solve for velocity at point 1

Where
 h = head loss Z = static head or elevation P = Pressure V = fluid velocity p = fluid density g = acceleration of gravity Q = flow rate
