Variables Used
Dynamic Pressure - (Measured in Pascal) - Dynamic Pressure is simply a convenient name for the quantity which represents the decrease in the pressure due to the velocity of the fluid.
Ambient Air Density - (Measured in Kilogram per Cubic Meter) - Ambient Air Density is the mass per unit volume of Earth's atmosphere.
Mach Number - Mach Number is a dimensionless quantity defined as ratio of speed of object to speed on sound.
Specific Heat of Air - (Measured in Joule per Kilogram per K) - Specific Heat of Air is the heat required to raise the temperature of air by one degree to that required to raise the temperature of an equal mass of water by one degree.
Gas Constant - (Measured in Joule per Kilogram per K) - Gas Constant is a general constant in the equation of state of gases that is equal in the case of an ideal gas to product of pressure and volume of one mole divided by the absolute temperature.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
