How is discharge flow rate calculated?
The flow rate of a stream is equal to the flow velocity (speed) multiplied by the cross-sectional area of the flow. The equation Q=AV (Q=discharge rate, A=area, V=velocity) is sometimes known as the discharge equation.
What is rate of discharge?
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.
What is the difference between flow rate and flow velocity?
Rate of flow, or simply flow, is the quantity of water, for example, that flows in a tube or other medium, in an interval of time. Examples: 2 kg of water per second, or 100 cubric meters of air per minute. Velocity is how fast the water, air or other fluid is moving in a tube or other medium.
What is the flow rate of a 1 inch pipe?
Water Flow (GPM/GPH) based on Pipe Size and Inside/Outside Diameters
| Assume Average Pressure (20-100PSI). About 12 f/s flow velocity | ||
|---|---|---|
| 1/2″ | 0.5 – 0.6″ | 14 |
| 3/4″ | 0.75 – 0.85″ | 23 |
| 1″ | 1 – 1.03″ | 37 |
| 1-1/4″ | 1.25 – 1.36″ | 62 |
What is discharge in pipe?
discharge pipe – a pipe through which fluids can be discharged. hydrant – a discharge pipe with a valve and spout at which water may be drawn from the mains of waterworks. pipage, pipe, piping – a long tube made of metal or plastic that is used to carry water or oil or gas etc.
What is the unit of rate of flow of discharge?
Flow rate or discharge, Q, is the volume of water in cubic feet passing a flow section per unit time, usually measured in cubic feet per second (ft3/s).
Is higher discharge rate better?
Fast charge a standard battery In severe cases, you can cause an internal short circuit and/or even an explosion. Most consumer applications require only 1C from their batteries. If you need higher discharge rates and faster charging times, you should definitely choose a high rate battery instead.
What is difference between flow and fluid?
As nouns the difference between flow and fluid is that flow is the movement of a fluid while fluid is (physics) any substance which can flow with relative ease, tends to assume the shape of its container, and obeys bernoulli’s principle; a liquid, gas or plasma.
What is Q VA?
One of the fundamental principles used in the analysis of uniform flow is known as the Continuity of Flow. Q=VA, when flow is constant, as velocity increases, the flow area decreases and vice versa.
What is meant by discharge in fluid mechanics?
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.
What is the flow rate of a 3/4 inch pipe?
Water Flow (GPM/GPH) based on Pipe Size and Inside/Outside Diameters
| Assume Average Pressure (20-100PSI). About 12 f/s flow velocity | ||

| 3/4″ | 0.75 – 0.85″ | 1,410 |
| 1″ | 1 – 1.03″ | 2,200 |
| 1-1/4″ | 1.25 – 1.36″ | 3,750 |
What is flow rate and discharge in flow rate?
Discharge (also called flow rate) The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate.
What is the formula for discharge in fluid mechanics?
The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate. Volume flow rate, Q = A v
How do you find the discharge of a material?
If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate.
What is flow rate in fluid mechanics?
Flow rate is basically defined as the quantity of a fluid flowing through a section of pipe or channel per unit time. For incompressible fluid, such as water, flow rate will be defined as the ratio of volume of fluid flowing through the section and time.
