A 4-stoke cycle C.I. engine develops 11KW per cylinder while running at 1800 rpm and using fuel oil of $32^o$ API.

A 4-stoke cycle C.I. engine develops 11KW per cylinder while running at 1800 rpm and using fuel oil of 32° API. Fuel injection occupies 32°C of crank travel and takes place through a fuel injections orifice 0.47 mm diameter with a flow coefficient of 0.9. Fuel is injection at a pressure of 1118.2 bar in to combustion chamber where the pressure is 31.38 bar. Estimate the quantity of fuel injected in kg/Kwh.
