How is pump discharge calculated?
Calculating the desired flow rate of your pump is quite easy. Let's say, you want to transport 300 litres of a fluid every 30 minutes, then your pump system has to transport 300/30 = 10 litres per minute or 0.167 litres per second. This is the desired flow rate, which is usually calculated before the installation.
Discharge = V x D x W
If length is measured in feet and time in seconds, Discharge has units of feet3/sec or cubic feet per second (cfs). Depth times Width gives the cross-sectional area. The shape of the channel is important because of the reduction in velocity due to friction along the channel margins.

- Centrifugal Pumps:
- The discharge of a centrifugal pump is given by:
- Q = (π × D × B × Vf)
- where Q = Discharge, Vf = Flow velocity, D = Diameter of the impeller, B = Width of the impeller.
More specifically, water discharge, which is the volume of water moving through the cross section of a stream or river during a particular unit of time, is typically computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section.
TOTAL DISCHARGE DAYS - The sum of the number of days spent in the hospital for each inpatient who was discharged during the time period examined regardless of when the patient was admitted.
volume = π (pi) × radius squared × length. volume = 3.14159 × (. 5 x . 5) × 600.
Discharge head refers to the vertical distance a pump must push fluid in order for the fluid to reach the system's highest point above the pump level. This is one of the factors that determine the size and power of your pump.
1 HP Single Phase Submersible Pump, Maximum Discharge Flow (LPM): 100 - 500 LPM.
A rule of thumb for pipeline head loss is doubling the flow rate increases the head loss by a factor of four. This is because the flow rate is raised to the second power.
What is pump discharge capacity?
The capacity of a pump has two components, the pump discharge rate and the discharge pressure. The discharge rate is normally measured in gallons per minute (gpm) in English units or liters per second (lps) in metric units.
Total Dynamic Head (TDH) = (Static Water Depth + Drawdown + Additional Lift) + Frictional Losses in Pipe.
A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass.
Discharge or rate of flow (Q) is defined as the fluid flowing per second through a channel or section of a pipe. This rate of flow is expressed in terms of “volume” when the fluid flow is incompressible and is taken in terms of “weight” when the flow is compressible.
Discharge time is basically the Ah or mAh rating divided by the current. The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
In order to determine the Flow Rate represented as Q, we must define both the volume V and the point in time it is flowing past represented by t, or Q = V/t. Additionally Flow rate and velocity are related by the equation Q = Av where A is the cross-sectional area of flow and v is its average velocity.
“Adjusted discharge” is the number of discharges multiplied by the ratio of total gross revenue to inpatient gross revenue and multiplied by the case-mix index and the wage index.
How do you calculate gravity flow through a pipe? First use the Hazen-Williams equation to find the velocity of the fluid: v = k × C × R0.63 × S0.54.
The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.

The discharge rate is defined as the steady current in amperes (A) that can be taken from a battery of defined capacity (Ah) over a defined period (h). Batteries for CEGB power stations are normally specified for a 10-hour rate.
Discharge Duration means the shortest period of time required by the Facility to reduce the State of Charge from one hundred percent (100%) to zero percent (0%) when discharging at Dmax as evidenced by the Performance Tests.
