The old compressor had seized up and typically when that happens it will send metal pieces ...Pitot tubes were invented by Henri Pitot in 1732 to measure the flowing velocity of fluids. Basically a differential pressure (d/p) flow meter, a pitot tube measures two pressures: the static and the total impact pressure. The static pressure is the operating pressure in the pipe, duct, or the environment, upstream to the pitot tube.The turndown ratio of orifice meters is generally between 3:1 and 5:1. Another limitation is the substantial permanent pressure loss caused by the obstruction created by the orifice plate. This makes orifice meters unsuitable for low-pressure systems as the additional pressure drop can significantly impact the overall system performance.The AC orifice tube on a 1997 Chevrolet Cheyenne 4.3 ltr vortec v-6 truck is located in the small inlet tube of the evaporator.
