Variables Used
Choked Mass Flow Rate - Choked Mass Flow Rate refers to the maximum mass flow rate of a compressible fluid through a restricted flow area, reaching the critical sonic conditions.
Mass Flow Rate - (Measured in Kilogram per Second) - Mass Flow Rate represents the amount of mass passing through a cross-section per unit time.
Specific Heat Capacity at Constant Pressure - (Measured in Joule per Kilogram per K) - Specific Heat Capacity at Constant Pressure means the amount of heat that is required to raise the temperature of a unit mass of gas by 1 degree at constant pressure.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Nozzle Throat Area - (Measured in Square Meter) - Nozzle Throat Area is the area of cross section at the throat of nozzle.
Throat Pressure - (Measured in Pascal) - Throat Pressure is the amount of discharge pressure of an engine at a given mass flow rate through the throat of the nozzle.
STEP 1: Convert Input(s) to Base Unit
Mass Flow Rate: 5 Kilogram per Second --> 5 Kilogram per Second No Conversion Required
