Arabella Weir, who happens to be strolling past, suggests putting a half tennis ball over the lock, "then smash it with the palm of your hand and the air pressure forces the lock up".
Inlet air pressure forced reactor gas out of the top of the reactor.
Subsequently, the endoscopes were flushed with sterile distilled water and dried with forced air (high pressure forced air with a 25 L/min airflow and 60 psi pressure to ensure more thorough drying of the internal channels of the GI endoscope after a complete HLD reprocessing cycle).
Wind and air pressure are forces, or energies, and if experts ignore these invisible forces and only watch and evaluate those elements of nature that can be seen (clouds), their skills at predicting weather will be embarrassingly poor.
But that night in Manchester, when marginal gains were in their infancy, the air pressure was low, forcing up air density (the denser the air the harder it is to push through) and the temperature cool and dry.
While there are less high-tech ways of taking the weight off your feet (such as running in water) the Alter-G uses air pressure as the lifting force, so that you can maintain normal running (or walking) biomechanics without the associated forces.
In both cases, the purpose is to distribute two forces -- air pressure and shear stress -- evenly.
There was almost a disaster when air pressure on the plane forced open the jar carrying the starter – a fermented mixture of water and wild yeast that is used to help the bread rise.
He cites a series of pleats arranged so that when the insect flaps downward, air pressure below the wing forces the trailing edge to stiffen and curve down in a classic airfoil shape.
In the vacuum of space, the air pressure inside the Alan Bean would force the hatch closed and airtight.
It featured automatic water dosing — in a sense, the first automatic anything on an espresso machine — and it employed a "double steam boiler" system, as the patent describes it, which used air pressure, rather than steam, to force water through the ground coffee (so the coffee was no longer scorched).
