I can not provide an estimate.
In calculation of flow out of a pipe, more information would be needed. Since you have asked this under the category of the oil spill, I assume you are asking what is the flow of oil out a vertical pipe, if the pressure at the bottom is 40,000 psi, and the diameter is 21". You need to specify the length of the pipe and all properties of the fluid. Since you are asking this in relation to the BP oil spill, gas will come out of solution as the oil is coming to the surface (or sea floor) making the calculations far from simple. There are a number of commercial pipe flow simulators.
Again, for the BP spill, a team of scientists and engineers are using pipe flow simulation , if possible, and other methods to estimate the flow.
The factors affecting the flow of liquid in a pipe include the pipe diameter, the viscosity of the liquid, the pressure difference across the pipe, the length of the pipe, and the roughness of the pipe walls. These factors collectively determine the flow rate and efficiency of the liquid moving through the pipe.
The velocity of flow in any pipe is determined by three things. The internal pipe diameter, the mass flow rate of the liquid and the fluid density.
of course liquid can flow through a pipe?
To calculate the pressure in a pipe based on the flow rate and diameter, you can use the formula for pressure drop in a pipe, which is given by the equation: Pressure (4 flow rate viscosity) / (pi diameter2) Where: Pressure is the pressure drop in the pipe Flow rate is the rate at which fluid flows through the pipe Viscosity is the viscosity of the fluid Diameter is the diameter of the pipe By plugging in the values for flow rate, viscosity, and diameter into this formula, you can calculate the pressure in the pipe.
A device for controlling the flow of liquid can sometimes be a pipe.
I want to know based on flow and pressure how to calculate diameter of the pipe
Smaller diameter = Greater pressure
That depends on the diameter of the pipe.
Assuming that the pressure remains at a constant, reducing the diameter of the pipe will increase the water flow. On the contrary, increasing the diameter would cause the water to flow at a much slower rate.
A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
In a fluid system, the relationship between pipe diameter, pressure, and flow is governed by the principles of fluid dynamics. A larger pipe diameter allows for higher flow rates at lower pressures, while a smaller diameter results in higher pressures needed to achieve the same flow rate. This is known as the relationship between pressure drop and flow rate in a fluid system.
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.
