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.

what is the discharge flow of 10m/s passing from 2ft pipe
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.
Please restate the question. Do you mean 3 inches. Are you asking about flow rate.
1.Flow Rate 2.Inside diameter of the pipe 3.Roughness 4.Corrosion and Scale Deposits 5.Viscosity of the liquid 6.Length of the pipe 7.Fittings 8.Straightness of the pipe
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!
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.
What pressure or are you asking drainage THEN What pitch are you using
1/2 OD or ID as copper is measured by OD BUT in plumbing rather then saying 5/8 L tubing we say 1/2 BUT 1/2 in ACR work is actually plumbers 3/8 The flow rate is about 7.5 to 10gpm Plenty for up to 3 low flow shower heads.
