Use Mannings Equation: Q=(1.486/n)*(A)*(R)^(2/3)*S^(1/2) Q = Flow (CFS) n = Roughness Coefficient A = Cross sectional flow Area of Fluid (FT*FT) R = Hydraulic Radius (FT) S = Slope (FT/FT)
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.
If we assume that the pipe is completely full of oil, it would just be the volume of the pipe = pi * r2 * l, where pi = 3.14159, r = radius, and l = length of the pipe. If the pipe is not full, then multiply the volume by the percentage of oil in the pipe. For example, if 50% full, then multiply by .5. If the pipe bends, take into account the different volume of the bend. If the bend is 90 degrees, this can be accomplished by taking the average length of the two bent segments for the length.
by multiplying the pipe size with the number of welded joints.regardsZH
There is no way to tell as the rate of flow is only partially influenced by pressure and there are many other contributing factors such as the diameter of a pipe or the viscosity of a liquid.
That depends entirely on the viscosity of the liquid in the pipe ! Water would flow faster than oil !
I want to know based on flow and pressure how to calculate diameter of the pipe
You would still need the coefficient of friction for the type of pipe in order to calculate flow.
high conductivity
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

Before you can calculate the flow, you must also have the pipe size and its coefficient of friction.
It is a check valve that will give almost the same flow as a pipe of the same dia. A lot of check valves will cut the flow rate down,sometimes a lot. A full flow will cut it a small amount.
The flow-line of a pipe is the bottom inside portion of the pipe. Flow-lines are generally reffered to when establishing the elevation of the pipe work.

Insufficient information, one needs to know the pressure of the water entering the pipe, the relative heights of both ends the pipe, the pressure of the water at the discharge of the pipe, the geometry of the pipe including the number and types of turns, and the pipe material or internal friction coefficient. Then you can calculate the flow.
Most plumbing or pipefitting suppliers have charts that show what size pipes you need to provide the proper flow rates at various pressures.
of course liquid can flow through a pipe?
