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:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:v=8sqrt{(RT_1/z) (1-(P_2/P_1)^z)}

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

::R is the common gas constant

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

::T1 is the absolute temperature at pressure P1

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

::z is egin{matrix}{c_p - c_v over c_p}end{matrix}

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:::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

Bernoulli's principle: Bernoulli's principle states that in fluid flow, an increase in velocity occurs simultaneously with decrease in pressure. It is named for the Dutch/Swiss mathematician/scientist Daniel Bernoulli, though it was previously understood by Leonhard Euler and others. For a mathematical formulation, see Be...
