Jet
- For alternative meanings, see Jet (disambiguation).
A jet is a stream of fluid produced by discharge through an orifice into free space.
Since gases are compressible fluids, the velocity attained by a jet of gas cannot be determined by Bernoulli's principle. Instead, if one uses adiabatic expansion from P1 to P2 in a properly shaped nozzle, the ideal velocity of a gas jet is:
- R is the common gas constant
- T1 is the absolute temperature at pressure P1
- z is
- cp is the specific heat at constant pressure
- cv is the specific heat at constant volume
- z = 0.286 for air under 500 °C
- z = 0.23 to 0.28 for most combustion products of fuels
