Hello, Velocity in a pipe is the flow divided by the area. If the pipe is full, the area is simply pi*r². Here is a useful calulator for full pipes: http://www.tasonline.co.za/toolbox/pipe/velocity.htm

How do you find the velocity of water if you know only the pressure and the size of the pipe?
It's lacking the temperature of water to calculate its velocity having the pressure and the diameter of the pipe. The temperature of water also counts on this equation. The equation is valid for fresh water, if the density of the water is higher compared to the fresh water, the result will vary, too. It is lacking also the inner condition of the pipe. Smooth or rough. The pipe must be placed horizontally, 0º degree of inclination. The pipe must be fully straight, too.
What is average velocity of water in pipe?
The average velocity of water in a pipe depends on the flow rate of the water and the cross-sectional area of the pipe. It can be calculated by dividing the flow rate by the cross-sectional area. The units are typically expressed in meters per second.
Can you calculate water velocity in pipe if just know head pipe diameter and pipe length?
Yes, it is actually one of the questions on a master plumbers exam
What is the volume of water in a five inch pipe?
Depends on the internal diameter, and the flow velocity. Velocity of water = Delta V Internal Radius= R RxRxV= Volume
How do you calculate air velocity through a round pipe?
to find the velocity of water in a pipe use the equation Q = VA where Q = the total volume of water running through the pipe in cubic feet per second V = the velocity of the water A = the cross sectional area of the pipe. (remember area = r^2*pi or D^2/4*pi). If you have the radius in inches find the area in inches and divide by 144 (1 square foot) this will yield the area in ft^2. you need to know how much water is running through the pipe (Q) - say 5 cfs and the area of the pipe (A) - say 1 ft^2 rearrange the previous equation V = Q/A and you get V = 5cfs/ 1 ft^2 = 5 fps
Formula for calculating the velocity of water in a pipe?
You need to know the cross sectional area of the pipe, this would be in square feet or square meters. Then take the volume flow in cubic feet per second, or cubic meters per second, and divide it by the area, this will give the velocity in ft/sec or m/sec V=(21.22*Q)/D2 V = velocity D= diameter of pipe Q= flow
Can you calculate pipe diameter if you have pressure head and discharge flow?
Static pressure is .434 X height Example 10 ft x .434 4.34 PSI to prove take 2.31 PSI x 4.34 To find FORCE to need to calculate the diameter of the piping and the height and then the weight of the water inside the pipe
What is maximum velocity in HDPE pipe?
Velocity of a fluid particle at centre of pipe is?
The velocity of a fluid particle at the center of a pipe in a fully developed flow is half of the maximum velocity in the pipe. This is known as the Hagen-Poiseuille flow profile for laminar flow.
What is max allowable water velocity in steel pipe?
Maximum allowable water velocity is generally kept as 3m/sec. But we have seen higher velocities also work.
How do you find the maximum and average velocities in the pipe as well as the volume flow rate?
To find the maximum velocity in the pipe, you would measure the highest speed at any point. The average velocity is typically calculated by dividing the total distance by total time. The volume flow rate can be determined by multiplying the cross-sectional area of the pipe by the average velocity.
What will be the flow if water flows in the uniformly varying pipe?
flow is proportional to velocity so its dependent on how fast the waters moving and the size of the pipe... check out the hazen williams nomograph
