Once the exhaust pressure has fallen to near atmospheric level the piston uncovers the transfer ports.

The exhaust pressure is controlled by a regulating valve to suit the needs of the process steam pressure.

Tuck clicked off the radio, pushed the throttles up, and watched the jet exhaust pressure gauges.

For many senior officers, the unceasing, sometimes exhausting pressure to produce ever-impressive declines in crime has also given success a sour taste.

The higher exhaust pressure and temperature combined with the increased mass flow is enough to keep the turbocharger spinning at high speed thus reducing lag.

This system changes the angle of the guide vanes depending on the exhaust pressure, giving the system excellent power throughout the rev range.

I'm just writing down things I need to remember, you know, climb rates and engine exhaust pressures, fuel consumption per hour at altitude, stuff like that."

The fact that the draught depends on the exhaust pressure means that power delivery and power generation are automatically self-adjusting.

The more volume that is swept by the piston, the lower is the exhaust pressure (in this case, the muzzle pressure).

The rockers are of roller type on the intake side, but high exhaust pressure limits their use to the intake side only.

Another difficulty is that the higher exhaust pressure causes the exhaust gas to transfer more of its heat to the mechanical parts of the engine.

This is an undoubted tribute to Mr. Mandela's unfailing grace under exhausting pressure.

For unequal intake and exhaust pressures, the correction factor for a small range of values may be taken from a graph in Report No. 45.

Not only did this result in a loss of exhaust pressure to drive the turbochargers but also the driving cabs rapidly filled with exhaust fumes.

This high-temperature high-pressure gas enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process.

This exhaust flame may show shock diamonds, which are caused by shock waves formed due to slight differences between ambient pressure and the exhaust pressure.

An air-cooled condenser is however significantly more expensive and cannot achieve as low a steam turbine exhaust pressure as a water-cooled surface condenser.

I whipped through first, second and third gears, and the engine emitted a sonorous wail at about 4,500 r.p.m. when the exhaust pressure bypass valves released.

Most turbopumps have a Holweck pump (or molecular drag pump) as their last stage to increase the maximum backing pressure (exhaust pressure) to about 1-10 mbar.

A full oscillation of the Helmholtz resonance occurs before the exhaust valve is closed, and to increase low-speed torque, large-amplitude exhaust pressure waves are artificially induced.

Turbocharging allows for more efficient engine operation because it is driven by exhaust pressure that would otherwise be (mostly) wasted, but there is a design limitation known as turbo lag.

More advanced exhaust brakes have exhaust pressure modulation (EPM) that controls the back pressure which in turn improves the braking performance across a range of engine speeds.

When the intake and exhaust pressures are equal, it is best to use an equation based on the work of NACA Report No. 46 for the pressure correction factor.

Noise reducers for firearms are less effective than those for engines for two reasons: first, gas pressure in a gun barrel is much higher than exhaust pressure in a tailpipe.

When a gas turbine engine is optimized for shaft power output, the exhaust pressure and temperature are minimized for maximum thermal efficiency within the limits of a Brayton cycle engine.
