Discharge Formula
The following formula is used to calculate a discharge rate.
Q = V * A
- Where Q is the discharge rate
- V is the velocity of the fluid
- A is the area of the opening the fluid is moving through
Discharge Definition
A discharge is defined as the total rate of fluid moving through an opening, or discharging from that opening.
Discharge Example
How to calculate discharge?
- First, determine the velocity.
Measure the velocity of the fluid. For this example, we will say the velocity is 20 m/s.
- Next, determine the area.
Calculate the cross-sectional area the fluid is moving through. We will say this is 20 m^2 for this example.
- Finally, calculate the discharge.
Using the formula we find the discharge rate to be 20*20 = 400 m^3/s.
FAQ
Discharge is most often used to describe the volumetric flow rate of a fluid through an opening. In other words, how much of fluid is moving through an area every second.
