A loss of pressure resulting from friction as a fluid passes through a porous medium from one area to another.

Resistance to airflow created by an air filter. Measured in inches water gauge or Pascals. A lower pressure drop is generally preferred.

Resistance to flow. Defined as the difference in pressure upstream and downstream. ( 099)

The difference in pressure between two points in a system, caused by resistance to flow.

The difference between inlet and outlet pressure of any control device.

a concern in semiconductor fabrication plants because it can limit process gas flow

that pressure lost between any two points of a piping or duct system due to friction, leakage or other reasons

Similar to voltage drop in electricity. Air is forced through the system (airflow) by pressure. There is a pressure drop (a drop in pressure - PSI) in proportion to the length and diameter the airline. The formula looks like this: Length of Airline X Velocity of air squared /25000 X Diameter of airline

the difference in pressure between the inlet and outlet of any tube. The pressure drop represents the resistance of an open tubular or packed column to mobile phase flow. As a consequence, while the amount of material entering and exiting the column per unit time is constant, the flow rate u at the inlet is lower than at the outlet.

A measure of the resistance the gas stream encounters as it flows through an air control device or other piece of equipment.

The decrease in pressure from one point in a pipe or tube to another down stream. This is usually the result of friction of the water against the tube. High flow rates in small tubes give large pressure drop. Low flow rates in large tubes give low pressure drop.

Also referred to as resistance, the difference of the air pressure entering the filter and the air pressure exiting the filter at a stated flow and under given conditions. The pressure drop of a filter is a measure of its resistance to airflow through it. Typically expressed in inches of water column (gauge) or in Pascals.

Resistance to gas flow; may refer to pressure differential across the cloth, across the baghouse, or across the entire system. Units are usually inches of water

The resistance of a device to the flow of a fluid through it. The pressure drop of a filter is a measure of its resistance to air flow through it. Resistance is measured in inches w.g. in the Inch-Pound system of measurement (1" w.g. = 0.036 psi). It is measured in Pascals in the SI system.

Pressure drop through the heat exchanger shall be expressed as the difference in static pressure between the Entering Supply Airflow and the Leaving Supply Airflow.

The difference between the inlet and outlet pressures.

A decrease in water pressure between the softener inlet and outlet connections.

Loss of pressure in a compressed air system due to friction or restriction.

a loss of pressure that results from friction sustained by a fluid passing through a line, valve, fitting, or other device.

A measure of a filter's resistance to airflow through it. The difference between the static pressure upstream and downstream of the filters. Resistance is measured in inches w.g. in the Inch-Pound system of measurement or Pascals in the SI system. The greater the pressure drop, the greater the resistance to air flow through the filter. 1 in. w.g.= 248.8 Pascals (Pa).

Pressure drop is the loss of pressure that occurs when the melt is pushed into a section of the mould during the filling phase.

The pressure loss which is added to system pressure loss, due to the presence of the damper.

The loss of pressure due to a restriction, a long line, or a small diameter line.

Resistance to air flow; may refer to pressure differential across the cloth, across the baghouse or the pressure drop across the entire system.

Resistance to flow created by the element (media) in a filter. Defined as the difference between upstream pressure (filter inlet) and downstream pressure (filter outlet).

It is the increasing resistance to airflow as the filter clogs.

The loss of force applied over a filtering surface due to restriction of airflow.

1. A decrease in the water pressure (in psi) which occurs as the water flows. Pressure drop may occur for several reasons: internal friction between the molecules of water, external friction between the water and the walls of the piping system, or rough areas in the channel through which the water flows.

The loss in static pressure of a fluid (liquid or gas) in a system due to friction from obstructions in pipes, from valves, fittings, regulators, burners, etc, or by a breech or rupture of the system. Pressurization Testing - A technique used by energy auditors, using a blower door, to locate areas of air infiltration by exaggerating the defects in the building shell. This test only measures air infiltration at the time of the test. It does not take into account changes in atmospheric pressure, weather, wind velocity, or any activities the occupants conduct that may affect air infiltration rates over a period of time.

The differential pressure between two points in a system. The resistance to flow between the two points.

Pressure decrease, occurring from friction losses in a fluid system, from one point to another.

Pressure drop is a term used to describe the change in pressure across a system. For example, in a typical garden hose the pressure in the hose is 40 psi and at sea level the atmospheric pressure is about 15 psi. Therefore, the pressure drop across the nozzle is 25 psi.

Pressure Drop is Robert Palmer's second solo album, released in 1975. Palmer is backed by members of Little Feat and other musicians.
