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

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
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.
Velocity of a fluid particle at centre of pipe is?
Maximum
How does the length of a pipe affect pitch?
The sound produced by a pipe is due to standing waves that are formed in the body of the pipe. The fundamental frequency,f1, produced, is given by the formula : f1=v/2L , where v is the velocity of the wave and depends only on the physical characteristics of the mean (e.g. air density), and L is the length of the pipe. So if the length increases the frequency decreases.
What is a Pitometer?
It's not a unit of measurement, that's for sure. It's a piece of equipment that measures the relative velocity of fluid, such as in wastewater applications or in firefighting (when you want to know how fast and hard the water is coming through a particular piece of pipe).
What is the formula for calculating flow of water using the velocity and diametor of the pipe?
Velocity = PSI x 12.1 THEN 12.1 Sq.Example 65 PSI x 12.1 Sq - 28.04 FPS
How do you find out water velocity in pipe?
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
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 the formula calculating pipe lateral?
it is useful to calculate branch in any degree:play.google.com/store/apps/details?id=com.nasirstore.branch
What is the formula for fluid?
inside area of fluid conductor in centimeter square x velocity of fluid in centimeters per second/1000 = flow in litre per second simple formula: Q=a*v Q=Flow rate a=area of pipe v=velocity of fluid in the pipe

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 formula for calculating volume of a hollow cylindrical pipe in cubic meter per hour?
There isn't an answer to this question. Perhaps it needs to be re-phrased.
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 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.
Is it important to know if the plumbing fixtures are flush valve or flush tank when calculating water supply pipe sizes?
yes
What is the formula for figuring out how many gallons of water are in a pipe by the foot?
0.61 * d2 Where d is the diameter of the pipe in inches.
