head 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 interval flowed at a final rate of 30.4 MMscfpd at a flowing tubing head pressure of 913 psi and a choke of 82/64 inch.
After completion of the well, a zone from 12,578 feet to 12,644 feet was perforated in the lower basal sand that flowed approximately 18.5 million cubic feet per day of gas and approximately 54 barrels per day of water with a flowing well head pressure of 1916psig at 44/64 choke.
For refrigeration systems with VSD control of evaporative condenser fans, there is a complex tradeoff between reduced fan energy, increased compressor energy and other impacts of changing head pressure e.g.
Drill Stem Testing in A-Sand Unit of Upper Sand, Lower Goru Formation flowed 9.05 million cubic feet per day of gas at Flowing Well Head Pressure of 855 psi on 48/64' choke.
PPL stated that the well has flowed 12.1 mmcfd of gas, condensate of 157 barrels per day along with 35 barrels of water per day at flowing well head pressure of 2,290 psi on 32/64' choke.
The company said that the drill stem testing in the Massive Sand (Deept) of Lower Goru formation flowed, 18.6 MMscfd of gas, condensate of 160 barrel per day along with 65 barrel of water per day at flowing well head pressure of 1,307 psi on 56/64' choke, 12.1 MMscfd of gas, condensate of 157 barrel per day along with 35 barrels of water per day at flowing well head pressure of 2,290 psi on 32/64' choke.
Lenexa, KS, November 15, 2018 --(PR.com)-- The new 815LT Submersible Smart Level Transmitters are ideal for measuring the level in a vented tank, sump, reservoir, or slurry by measuring the hydrostatic head pressure. The vented cable design provides reference to atmospheric pressure so that accurate level readings can be achieved.
That length depends on the polymer viscosity, screw design and the head pressure.
(c) The seepage flow and pressure head are obtained by the boundary conditions, and the head pressure and the seepage flow in each lining structure were solved according to the relationship of the lining structures
But head pressure control and a reduction in condenser water flow through an operating chiller made our customer very nervous, uncomfortable, and more than a little skeptical.
As a result of drill stem test (DST) done to test the well's potential of Lockhart formation, the tests showed 2,020 barrels per day of rude oil, 5.4mmsefd of gas at 40/64' fixed choke size at the flowing well head pressure of 1,177 psi.
Water units often use a scaffold or lift truck to give enough head pressure to the water column.
