The exhaust pressure is controlled by a regulating valve to suit the needs of the process steam pressure.
2.
The fact that the draught depends on the exhaust pressure means that power delivery and power generation are automatically self-adjusting.
3.
This system changes the angle of the guide vanes depending on the exhaust pressure, giving the system excellent power throughout the rev range.
4.
The total energy produced by an engine, of course, being mechanical, heat, exhaust pressure, and a tiny bit as sound and engine wear.
5.
The 349 passengers and crew got off the 747, which had developed problems with the exhaust pressure gauge in the No . 3 engine.
6.
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.
7.
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.
8.
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.
9.
Further along the exhaust pipe, the exhaust pressure wave encounters a converging conical section, and this reflects a " positive " pressure wave back up the pipe.
10.
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.
