The relationship between pressure and flow is given by Bernoulli's law. In an idealized system, the speed increases with the square of the increase in pressure. The flow rate would be given by multiplying the area of the outflow by the speed.

What is the function of an impeller?
An impeller is used in many devices, such as a washing machine and water jet. An impeller is used to control the pressure and flow of water. It is found inside of a tube or a conduit, an impeller is a type of rotor.
What Differential Pressure Transmitters Do?
Differential pressure transmitters were originally designed for use in pipes to measure pressure before and after the fluid encounters a filter, pump, or another interruption in flow. Standard differential pressure transmitters come with two process connections arranged side by side to measure the drop in pressure (d) between the higher and lower points (H and L, respectively, in Figure 1). Classic differential pressure transmitters can also measure flow rates. It wasn’t long before people realized that differential pressure measurements could be used to determine liquid level as well.
What is coefficient of volume?
Coefficient of Volume (Cv) is a factor used in describing the amount of water that will pass through a fully open valve. It describes the flow in gallons per minute (GPM), with a specific gravity of 1, at a temperature of 60 deg F, and a pressure drop of 1 psi. For example, a Cv of 6.0 indicates a flow capability of 6.0 GPM at the above mentioned conditions. For a pressure drop of other than 1 PSI, GPM = Cv*Sqrt(delta P / Specific Gravity), where delta P is in unit of PSI.

How do you convert 721 lbs into kg per second?
You cannot. A pound is a measure of mass while a kilogram per second is a measure of flow rate. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
What is the average flow rate of water within a 32mm pipe at UK mains pressure?
30 litres per minute
Air measured is 6 liter per minute on a water flow controler. How do you convert water flow to air flow?
The reading you got of 6 litres per minute on air with a water flow controller cannot really be converted because the properties of the measured things are completely different the flow controller is used to measuring a hydraulic medium instead of a compressible one for example.
How to convert air flow into water flow?
If you have the air flow velocity and pressure drop for at least three points, plot the pressure as a function of the velocity; P=av2+bv. Use the trendline plotting function in Excel to get the two constants or solve the simultaneous equations for two of the points. Then convert the constant "a" from air to water by multiplying by the ratio of the water density to the air density, which is around "834". Convert the constant "B" by multiplying by the ratio of the dynamic viscosity of water to air, which is around "52". The equation will generate the pressure "P" and velocity values "v" that would occur if the fluid were water instead of air.
What powers the flow of water?
Normally gravity, but osmotic pressure can also cause water to flow.
Can a flow meter measure my water pressure?
Yes you can use a flow meter to measure your water pressure. They are available at any home improvement retailer.
Does a water meter only measure the time that the water is flowing past it assuming that the water is always flowing at a constant pressure?
No. Most water meters are of the positive displacement type. They meter actual volume, and are pressure independent. Also note that water flow and pressure are not the same thing. You can have high flow with low pressure, and also low flow with high pressure, depending on the size of the pipe and/or openings (such as valves) and the pressure.
How can you make water flow without pressure?
Of course
What condition necessary for the sustained flow of water in a pipe?
negative pressure is needed for a sustained flow of water in a pipe.
What condition is necessary for the sustained flow of water in a pipe?
negative pressure is needed for a sustained flow of water in a pipe.
How do you convert millimeter h2o into Cubic Feet per Minute?
You can't convert those units. Milimeters of water (mmH2O) is a unit of pressure equal to about 13.6 mmHg. Cubic feet per minute is a measure of fluid flow.
What specifically creates hydraulic flow?
Hydraulic literally means 'moving fluid'. A volume of fluid that is displaced by another given volume, be it solid or fluid, has a flow of that volume of displacement measured in volume / time. For example: litres / minute. A hydraulic pump may provide a flow of 10 litres per minute. This flow may be turbulent or laminar. Do not confuse this with pressure.
Why draft tubes are immersed in water?
to reduced the back flow of water because when water comes out from the runner the pressure is lower then the atmospheric pressure due to this back flow is generated.
