| 21. | As such the seal air is controlled by a local control damper maintaining just sufficient differential pressure for sealing.
|
| 22. | Balancing valves allow the measurement of differential pressure and temperature thereby pinpointing the cause of many such operational problems.
|
| 23. | The small orifice size maintains differential pressure in the microscope ( vacuum ) and deposition chamber ( no vacuum ).
|
| 24. | A "'DP cell "'is a device that measures the differential pressure between two inputs.
|
| 25. | Differential pressure gauges have two inlet ports, each connected to one of the volumes whose pressure is to be monitored.
|
| 26. | An airspeed indicator is a differential pressure gauge with the pressure reading expressed in units of speed, rather than pressure.
|
| 27. | Therefore, inductive pumps may be used in very high pressure closed circuits to circulate liquids at very low differential pressures.
|
| 28. | Four test cocks are installed to allow an inspector to verify proper operation of the valve with a differential pressure meter.
|
| 29. | The aircraft is pressurized and was designed for a differential pressure, giving an cabin pressure at its maximum altitude of.
|
| 30. | The streaming potential appears when mud filtrate is forced into the formation under the differential pressure between mud column and formation.
