    Torque has been defined as 'that which produces or tends to produce rotation.' To the dentist, this means at what finger pressure does the cutting tool stall or stop. Quick stalling or low torque is desirable for safety, but there is a point of diminishing return. Most turbines, particularly with low air pressures, stall much too quickly.

    2 天前 · Another little known fact about compressed air from an end user’s point of view is that discharge pressure has a direct impact on flow. In fact, we know from Boyle’s Law that: P1 x V1 = P2 x V2. Where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume.

    2021-5-13 · Most modern passenger and military aircraft are powered by gas turbine engines, also called jet engines. The first and most simple type of gas turbine is the turbojet. In the turbojet engine, large amounts of the surrounding air are brought into the engine through the inlet. The air pressure and temperature are increased by the compressor, which performs work on the flow.
