What is the formula for calculating pipe size?
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..
What is the formula for volumetric flow rate?
So, we get a new formula for the volume flow rate Q = A v Q=Av Q=AvQ, equals, A, v that is often more useful than the original definition of volume flow rate because the area A is easy to determine.
How do I calculate flow rate?
The flow rate formula, in general, is Q = A × v, where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point.
How much water can flow through a pipe?
Here are the average water flow rates based on typical municipal water lines: ½-inch pipe: 50 gallons per minute. ¾-inch pipe: 110 gallons per minute. 1-inch pipe: 210 gallons per minute.
How do you calculate the velocity of water in a pipe?
Poiseuille’s Law states that flow rate F is given by F = π(P1-P2)r4 ÷ 8ηL, where r is the pipe radius, L is the pipe length, η is the fluid viscosity and P1-P2 is the pressure difference from one end of the pipe to the other.
How much water will flow through a 2 inch pipe?

Does pipe size affect flow rate?
In general, the flow rate increases proportional to the square of the inside diameter, hence the flow rate is directly proportional to the area of pipe cross-section. The larger the diameter, the greater flow.

How do you calculate flow rate and pressure in a pipe?
Divide the pipe’s internal diameter by 2. For example, if the pipe has an internal diameter of 0.1 meters: 0.1 ÷ 2 = 0.05 m This is the pipe’s radius. Square this radius: 0.05² = 0.0025 m².

How do you calculate water discharge?
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.
