The first large scale venturi meters to measure liquid flows were developed by clemens herschel who used them to measure small and large flows of water and wastewater beginning at the end of the 19th century.
Water jet pressure measurement.
Water jets accelerated by differently configured convergent nozzles of diameters ranging from 4 5 to 5 0 mm are studied.
The jet strength at the outlet of the nozzle is found to increase by a factor of 4 0 4 5.
This type of pressure measurement may be more convenient for example to measure fuel or combustion pressures in jet or rocket engines.
For more explanation see water pressure measurement.
If the vertical distance from the pitless adapter to the point at which water enters a two line jet pump system foot valve in the well is 100 feet the water pressure or static head pressure that the pump has to overcome will be 100 x 0 43 43 psi if we presume that the rest of the piping in the system from foot valve to pump and pressure.
Install a permanently mounted water pressure gauge.
Velocity measurements are carried out with a spring dynamometer and a free running pelton microturbine.
With high measurement accuracy and long term reliability the next generation in e series ultrasonic water meters are fully programmable and designed for replaceable electronics making them ideal for measuring potable cold water in commercial and industrial applications.
The formation of these discrete pulses of water with increased amplitude at p 40 mpa causes the repeated hammer effect on the surface.
If the predefined pressure was reached a valve opened directly at the cutter head and the water jet entered the pressure vessel.

A water booster can also sometimes be installed into to increase water pressure.
Afterwards the pressure was controlled by the valve.
Call your landlord or water company for pressure lower than 6 gpm.
The excess pressure at the nozzle inlet varies from 5 103 to 3 5 106 pa.
At low pressure of p 40 mpa the jet flow rate results into discrete formation of the clusters of water as compare of high pressure p 100 mpa up to standoff distance z 31 mm.
If you have under 6 gpm it means that you may have low water pressure.
For generating the pressure in the vessel a hand pump was used.
Using a mix of water pressure and granular abrasive to control power water jet cutting is an effective cutting option on a wide variety of materials.
Water jet cutting utilizes a high pressure stream of water to erode a narrow line in stock materials.
Boiler gauges measure both the temperature and water pressure in boilers.
Low pressure can be caused by blocked pipes leaking pipes or a water supply malfunction.
Pressure gauges and vacuum gauges allow users to monitor the pressure of air and noncorrosive fluids in pumps filters compressors and regulators.
