Drop of pressure with closed vents (mmH2O

Drop of pressure with open vents (mmH2O

Finally, a pressure accumulator prevents a collapse of the pressure during an abnormal pumping operation.

The system includes a release apparatus actuatable by pressure reduction.

The pressure is reduced to atmospheric pressure either before or after removing the aerating device (6) from the dough.

The controller controls the metering of the fuel flow by the servo valve based on the pressure drop measured by the pressure transducer and the known fuel flow vs. pressure drop characteristic of the at least one calibrated nozzle.

Ammonia gas that is vaporized by the pressure reduction is recovered and reused.

In the distribution passages the refrigerant shall be subjected to a pressure drop.

Melting due to a decrease in pressure (decompression)

Further, stepped and/or parallel arrangement of the absorber (21) results in reduced fluid pressure drop.

The system may provide for accelerated pressure drop on completion of a peeling operation, as well as including arrangements to minimise release of entrained solid matter and/or odours in exhaust steam.

The presence of the drag reducer in the treated fluid reduces pressure drop associated with flow through the production/transportation conduit.

The pressure drop Δ pfilter across the particle filter (10) is measured by a first differential pressure measurement device (21).

Gas flow is a function of inlet pressure and temperature, pressure drop between the SSV inlet and throat.

The mass flow rate is a function of the pressure drop across the restrictive orifice resulting from the pressure differential between the depleted gas and the source gas.
