41+ how to calculate exit velocity of nozzle

At an absolute pressure entering the nozzle p 70 MPa and exit the rocket. The a in the formula is the acceleration of the exhaust from injection to whatever that exit velocity is v in the time it.

Nozzle Anatomy Nozzle Flow Rate Pnr Italia

Web The flow rate for a given nozzle can be calculate by the following formula.

. V e T R M 2 γ γ 1 1 P e P γ 1 γ where. Values of the index n and the critical pressure ratio r for different fluids are given in the table below. Web The static pressure at the exit of the nozzle is equal to free stream static pressure unless the exiting flow is expanded to supersonic conditions.

Web The maximum gas flow through a nozzle is determined by critical pressure. Web The formula to calculate exit exhaust velocity is. Web Throat Velocity Equation.

N Is a constant that. K K factor for nozzle. In this case it is equal to 3225 m s.

V e is exhaust velocity. Web As an example calculation using the shown equation assume that the propellant combustion gases are. P Pressure differential at the nozzle.

A v t. Web Velocity in a Nozzle. Critical pressure ratio is the pressure ratio where the flow is accelerated to a velocity equal to the local.

Web The nozzle flow exit velocity is now calculated 2160020858260100147003851612 To convert to feet per second multiply. And I also know that the Volume and Velocity. Web Go Velocity sqrtHead loss at pipe exit2g Velocity of Flow at Outlet of Nozzle Formula Flow Velocity through Pipe sqrt2gHead at base of nozzle 1.

For unit mass The steady flow equation is q w Δ h Δ PE Δ KE For a horizontal nozzle Δ PE 0 There is no work-done in nozzle therefore W 0. Web Why does exit velocity affect rocket thrust. T 2 P 2 P 1 R C P T 1 to find the exit temperature.

Web Therefore I would want to find the exit temperate using the following formula.
