Enter the coefficient of discharge, the diameter (ft), and the height (ft) into the Riser Pipe Flow Calculator. The calculator will evaluate the Riser Pipe Flow.

## Riser Pipe Flow Formula

The following formula is used to calculate the Riser Pipe Flow.

**Q = 6.3*Cd*d^2*h^.5**

Variables:

- Q is the Riser Pipe Flow (ft^3/min)
- Cd is the coefficient of discharge
- d is the diameter (ft)
- h is the height (ft)

## How to Calculate Riser Pipe Flow?

The following steps outline how to calculate the Riser Pipe Flow.

- First, determine the coefficient of discharge.
- Next, determine the diameter (ft).
- Next, determine the height (ft).
- Next, gather the formula from above = Q = 6.3*Cd*d^2*h^.5.
- Finally, calculate the Riser Pipe Flow.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

coefficient of discharge = .59

diameter (ft) = .75

height (ft) = 30

Q = 6.3*Cd*d^2*h^.5 =** ** ?
