A sonic converging nozzle with a negligible inlet velocity and inlet and throat areas of 2.00 in2 and 0.500 in2 , respectively, has a velocity coefficient of 0.820 when the upstream stagnation pressure and temperature are 100. psia and 70.0°F.
Determine the thrust produced by the nozzle in atmospheric air.
Almost the entire volume of mercury in a thermometer is contained in the bulb. The remainder extends up into a capillary tube. Find the inner radius of the capillary tube
The Sun generates most of its light during a series of nuclear reactions called the proton-proton chain. The overall process of these nuclear reactions can be summarized as4 1H → 2He + 2ν + 2γ + 2? Where ν is a small neutral particle called a neutrin..
