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.
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
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?
2460 m/s
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.
A tank is 65 feet high. A 4 inch diameter pipe is used to give water at the bottom of the tank. What is flow rate and velocity of water at the bottom of the tank. Please show me the formula. Thanks.?
The Head just before entry to the pipe becomes velocity Head at the exit of the pipe. Assuming no losses: H=u^2/2g --> u=Square root of (2gH) where H is the height of the height of the level of water in the tank above the outlet of the pipe and u is the velocity. The velocity is such that if the water left the pipe vertically upwards and assuming no losses of any sort, the water would stop at the same level as the water in the tank. The volume flow rate is then uA where A is the area of the pipe, ie (πd^2)/4 Make sure you use the same units eg, u in meters per second, d and H in meters, g=9.81 m/s^2
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
What is the effect on velocity and pressure if a liquid flows in a convergent pipe?
I think velocity is directly proportionate to its applying pressure.
Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
What is the equation for water flow in construction?
the velocity of water flow within a drainage pipe; the equation is V=L/t L= Length t=time. Then the flow rate; Fr=A*V, Where A= sectional area and V = velocity.
