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.

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.

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.
