inlet pressure

inlet pressure

i. The total pressure taken in the engine inlet as a measure of air density. This parameter is sent to the fuel control for fuel scheduling. It is normally known as P1 pressure.
ii. As it relates to the performance data on pumps, when not other-wise specified, the total static pressure measured in a standard testing chamber by a vacuum gauge located near the inlet port. Also called intake pressure, fine pressure, or head pressure.

This means a significant increase in inlet pressure and temperature (from an average of 190[degrees]C today to an estimated 246[degrees]C).
The valves are rated for 300 psig maximum inlet pressure at operating temperatures ranging from 40[degrees] to 120[degrees]F.
They are available as a fully UHV-compatible bolt-on instrument or with application-matched single or compound molecular beam inlet pressure reduction stages, addressing a range of atomic and molecular studies.
Specifications include a large digital pressure display and a multi-color LED status display, 3000 PSIG (210 BAR) maximum inlet pressure, 0[degrees]F to 140[degrees]F temperature range, and 50 to 250 PSIG (0 to 17 BAR) adjustable pressure range, 1.0 Cv.
Typical urea production conditions include an inlet pressure of 3,500 psig, an outlet pressure of 300 psig, an operating temperature of 350[degrees]F, and a flow rate of 8 million SCFH.
* No air entrapment: The high pump inlet pressure prevents air inclusions from reaching the gear teeth, so that air does not reach the die and thus is not contained in the preform produced.
It's "balanced." meaning that the outlet pressure, commonly known as back pressure, can be as high as the inlet pressure without affecting performance.
As inlet pressure and flow vary, pressure-reducing regulators are designed to maintain outlet pressure, deliver accurate, consistent pressure to processes and process equipment, and protect sensitive equipment.
Based on the I-D Darcy's law and constant inlet pressure, Cai proposed two principles of design: (1) the arrangement of the vents should assure the shortest filling path, and (2) the line gates or the gate should be arranged on the larger side such that the fluid be injected from the larger side to the smaller side and the applied pressure required is thus reduced.
This tandem arrangement helps with the higher-viscosity materials and ensures that the metering pump always "sees" the same inlet pressure, regardless of viscosity.
