Now consider the amount of pressure drop across the fully opened valve with such a small flow It will be especially small if the motor has a reasonably high volumetric efficiency When the maximum volumetric efficiency is between 80 and 95 the valve pressure drop at stall will be about 3 to 10 of the applied supply pressure

The Borewell FAQ Part I amp II are meant to provide a primer on the basics related to all aspects of borewells A well compiled document it also give links to relevant queries and provides a much needed starting point for all those contemplating a borewell
May 18 2020nbsp018332Turning off a highpressure flow of liquid or gas by obstructing it with a valve is physically hard work in other words you need to use a lot of force to do it Thats why some valves are operated by levers like the one photographed here but some can be much longer to give you more turning force or large wheels as in the top photo in this
The next step is to go to a point downstream of the control valve where the pressure is known for example a tank where the head is known and then work upstream toward the control valve adding the pressure loss of each of the fixed elements You are adding the pressure losses because you are working in the direction opposite to the flow
May 07 2019nbsp018332If you fire a gun into the air the bullet will travel up to a mile high depending on the angle of the shot and the power of the gun Once it reaches its apogee the bullet will fall Air resistance limits its speed but bullets are designed to be fairly aerodynamic so the speed is still quite lethal if the bullet happens to hit someone
Successful completion of an optional test does not relieve the manufacturer from also successfully completing the required test In the case of resilient seated valves a highpressure closure test may 176rade subsequent closure sealing performance in lowpressure applications
