With the information available, your question is unanswerable. The length of pipe,number and type of fittings and material( interior surface finish) must be known before the calculation can be made.

The pipe capacity equation, also known as the Manning formula, is used to calculate the maximum flow rate that a pipe can handle. It is expressed as Q (1.486/n)A(R2/3)(S1/2), where Q is the flow rate, n is the Manning roughness coefficient, A is the cross-sectional area of the pipe, R is the hydraulic radius, and S is the slope of the pipe.
what is the discharge flow of 10m/s passing from 2ft pipe
To calculate the volume of natural gas that can pass through a 3" diameter pipe at 1 psi, you would need to know the flow rate of the gas. Without this information, it is not possible to determine the volume of gas that will pass through the pipe.
To calculate gallons per minute (GPM) in a 3-inch pipe at 90 psi, you can use the hydraulic formula that relates pressure, pipe diameter, and flow rate. Generally, for a 3-inch pipe, the flow rate at 90 psi can be estimated to be around 1,000 to 1,200 GPM, depending on factors such as pipe length, fittings, and the specific fluid properties. For precise calculations, it's advisable to consider additional factors like friction loss and fluid viscosity.
1. It is used for flow measerment with minimum head loss. 2. It is used in industries for flow measerment of chemicals. 3. it is also used in the airoplane for measurment of speed of plane.
For laminar flow? For a full pipe? for a 3/4-full pipe? For a 1/2-full pipe? It all makes quite a difference. Please repost your question with a little more information. It would also help to for us to know the coefficient of friction of the inside of the pipe.

The standard formula to calculate flow(GPM - gallons per minute) from a CIRCULAR orifice is:29.7 * (the square root of the pressure) * (the square of the diameter of the flow orifice)EXAMPLE using 3/4" Pex Pipe(actual I.D. of 3/4 PEX Pipe is .677") and 40 PSI pressure:29.7 * 6.325(sq. root of 40) * .458(the square of the I.D. 3/4" pipe) =A GPM of 86.03Note: You also need to account for fittings in the loss calculations; while minimal several fitting will make a difference.
Simply continuity law apply: Q=AV Q= flow rate A=Area V= Velocity Normally velocity is around 1 m/s to 3 m/s.Pipe area calculted by it size. We get the answer of flow rate. Regards Nehal uddin. AM Projects
In order to effectively answer this question more factors would need to be known. The most important factor being the type of liquid flowing through the pipe. Different liquids have a different rate of flow, even with varying elevations.
Answer:10/3 hour = 3 Hour and 20 minutesSolution:the volume of cistern (V) = 1 volume unitflow rate of pipe A = 1/6 V/hourflow rate of pipe B = 1/8 V/hourVolume filled = flow rate * timein the first two hours the volume filled = 1/6 * 2 + 1/8 *2 = 7/12 V.Remaining Volume = 1-7/12=5/12the folw rate after two hours = 1/8 (just pipe B)required time for pipe B to fill the cistern = Volume / flow rate of the pipe B= 5/12 divided by 1/8= 5/12 * 8/1 = 10/3 hours = 3 and 1/3 hours = 3 hours and 20 minutes.Check:if the answer is correct the volume should be 1:Total volume = 1/6*2 + 1/8*2 + 1/8*10/3 = 1.so, the answer is correct.Cheers!
