Mass flow in air can be calculated if you know the pressure drop across the pipe. Then it can be calculated using Darcy's Equation for Pressure,which is: P2-P1 = (4fLv*v)/d*2*g where, P2 & P1 are pressures at two points in pipe, f = friction factor, L= length of pipe, v = velocity of fluid, d = diameter of pipe, g = gravity. from this formula we can calculate the velocity and hence the flow rate.

Pressure 14.5psi flow will be 700gallon per day how will calculate the pipe diameter?
I want to know based on flow and pressure how to calculate diameter of the pipe
Is there such a thing as a flow directional pipe-fitting union?
yes
How does cavitation relate to diameter of a pipe?
Vapor pressure is the main factor in determining cavitation. Vapor pressure is a dependent on temperature. A pipes diameter becomes a main factor because it directly reflects the velocity of the pipe. Velocity is an important factor in determining cavitation in a pipe since it effects the velocity head for a piping system. If the velocity head is to great it could decrease the pressure inside of the pipe causing cavitation. Example: For a given pipethe flow will constant for. However the velocity in the pipe is dependent on its diameter. This is because velocity is based on the ratio of flow to area. Flow will not change but based on the diameter of the pipe it will have a different velocity. If the pipe had varying diameters the velocity will vary as well. Higher velocities will be at areas where the diameter is small and slower at areas where the diameter is larger.
What is desilting pipe?
Silt in pipes is caused by solids suspended in liquids, that are flushed through the drainage system, settling in the pipe-work. This can be caused if there is a lot of solid matter flushed through the pipe system or if the flow is too slow or has too many turns causing the flow to been restricted (which in turn allows the solid particles held within it time to fall to the low point in the pipe). De-silting is carried out through either high pressure jetting or exposing the affected pipe-work and physically cleaning out. Silting can occur in other pipe systems, as well as drains, but depends on what the plumbing system is carrying. Hard water areas (high level on degrees Clarke) may need acid descale etc.
How Do you calculate the area of pipe?
Start with the maximum flow speed (metres per second) for your liquid, then mutiply by the area of the pipe in square metres, the result is maximum volume flow rate in cubic metres per second.
What is the basic hydraulic calculation for fire hydrant system?
A fire hydrant system consists of a network of pipes. Hydraulic calculations allow one to predict the flow and pressure at any particular point. Alternatively, it is a method of calculation to optimize the system by changing the pipe size or flow or pressure so that desired pressure or flow can be achieved at a particular point.

What are limitations of velocity of flow in a pipeline?
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.
Why dp created for flow measurement?
The primary element creates a pressure drop across the flow meter by introducing a restriction in the pipe, and this engineered restriction enables Bernoulli's equation to be used for a flow rate calculation.
Where is the mass air flow sensor on a 2001 Toyota Camry?
Mass air flow sensor is located in the intake pipe connecting the air filter box with the throttle body.
What is the flow rate in a 3 pipe at 225psi?
With the information available, your question is unanswerable. The length of pipe,number and type of fittings and material( interior surface finish) must be known before the calculation can be made.Go to http://www.efunda.com/formulae/fluids/calc_pipe_friction.cfm and fill in all the blanks and the calculation will be made for you>
What is flow line of a pipe?
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.

Can you liquid flow through a pipe?
of course liquid can flow through a pipe?
What is the liquid flow rate of a 21 diameter pipe at 40000 psi?
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.

In headloss calculation using hazzen William equation does units of flow and pipe diameter are cancelled out?
The Hazen-William equation is an empirical one. It has a proportionality constant that depends on the use of USCS units or SI units. For the case of USCS units, pressure drop is in 'psig', length of pipe in 'ft', volume flow in 'gpm', and inside pipe diameter in 'in'. For the case of SI units, pressure drop in 'm', length in 'm', volume flow in 'm3/s, and inside pipe diameter in 'm'.
