Fuel Velocity at Time of Release into Engine Cylinder Solution

STEP 0: Pre-Calculation Summary

Formula Used

Fuel Velocity at Tip of Nozzle = sqrt(2*Specific Volume of Fuel*(Injection Pressure-Pressure in Cylinder during Fuel Injection))
V₂ = sqrt(2*v_f*(P₁-P2))
This formula uses 1 Functions, 4 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

Fuel Velocity at Tip of Nozzle - (Measured in Meter per Second) - Fuel Velocity at Tip of Nozzle is defined as the velocity of the fuel when it is released from the fuel injector nozzle into the engine cylinder.
Specific Volume of Fuel - (Measured in Cubic Meter per Kilogram) - Specific Volume of Fuel is defined as the number of cubic meters occupied by one kilogram of fuel or matter.
Injection Pressure - (Measured in Pascal) - Injection pressure is defined as the pressure of the fuel at intake of fuel injector in pascals.
Pressure in Cylinder during Fuel Injection - (Measured in Pascal) - Pressure in Cylinder during Fuel Injection is defined as the pressure built up in the engine cylinder when the fuel is sprinkled from the fuel injector at the end of compression stroke.

STEP 1: Convert Input(s) to Base Unit

Specific Volume of Fuel: 1.18 Cubic Meter per Kilogram --> 1.18 Cubic Meter per Kilogram No Conversion Required
Injection Pressure: 140 Pascal --> 140 Pascal No Conversion Required
