Fuel Velocity at Time of Release into Engine Cylinder Formula

Fuel Velocity at Tip of Nozzle = sqrt(2*Specific Volume of Fuel*(Injection Pressure in pascals-Pressure in Cylinder during Fuel Injection))
V2 = sqrt(2*vf*(P1-P2))

What is fuel velocity when it is released from the fuel injector nozzle?

Many diesel engines use direct injection in which the diesel is injected directly into the cylinder filled with compressed air. The injectors through which the fuel is sprayed are screwed, nozzle-first, into either the inlet manifold or the cylinder head and are angled so that the spray of fuel is fired towards the inlet valve .
