The Discharge Height of Vertical Pipes calculator estimates the flow (F) volume from a vertical pipe based on the height (h) of discharge, the diameter (D) of the pipe and flow constant (k).
INSTRUCTIONS: Choose units and enter the following;
- (h) This is the height of the fluid above the pipe.
- (k) This is the flow coefficient. It ranges from 0.87 up to 0.97 for pipes with diameters between 2 and 6 inches, and for height up to two feet.
- (D) This is the diameter of the pipe.
Vertical Discharge (F): The calculator returns the flow rate in gallons per minute. However, this can be automatically converted to compatible units via the pull-down menu.

The formula for Volume of Vertical Discharge is:
- `F = sqrt(h)*k*D^2*5.68`
where:
- F is the flow rate in gallons per minute
- h is the height of the water plume above the pipe opening
- D is the diameter of the pipe
- k is a constant that ranges from 0.87 to 0.98 for heights up to 2 feet.
