    2014-1-9u2002·u2002In the air system a distinction is made between a turbine and an air motor. With turbines the bur is directly driven by a rotor. The rotor has an impeller powered by compressed air. Turbines reach an idle speed of up to 400,000 min-1. The working speed depends on the pressure exerted and is approximately half the idle speed - i.e. approx ...

    Water flow and pressure both are related to friction. As water moves through a pipe, friction will slow it to a certain degree, depending on the texture and diameter of the pipe. The smoother the pipe, the less friction there is and the faster water can move through the pipe, provided that the water pressure is sufficient.
