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.
