Actual Fuel Velocity of Injection Considering Orifice Flow Coefficient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Actual Fuel Velocity of Injection = Flow Coefficient of Orifice*sqrt((2*(Injection Pressure-Pressure in Cylinder during Fuel Injection)*100000)/Density of Fuel)
V_f = C_f*sqrt((2*(P₁-P2)*100000)/ρ_f)
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Actual Fuel Velocity of Injection - (Measured in Meter per Second) - Actual fuel velocity of injection is defined as the fuel velocity of injection in actual that is during the working of automobile engines.
Flow Coefficient of Orifice - Flow Coefficient of Orifice is defined as a relative measure of its efficiency at allowing fluid flow and the resultant pressure drop of the fluid.
Injection Pressure - (Measured in Pascal) - Injection pressure is defined as the pressure of the fuel at intake of fuel injector in pascals.

What is the fuel velocity at fuel injector tip?

The fuel then squirts out into the inlet port in the cylinder head. Each injector contains a spring-loaded valve that is kept closed by its spring pressure. The valve only opens when the fuel is squirted in. The fuel has a certain velocity when it travels through the fuel injector and with this velocity it comes out of the nozzle of the fuel injector at the end of compression stroke of the diesel engines.
