7 A four-cylinder, four-stroke SI engine, having a bore of 10 cm and stroke 9 cm runs at 4000 rpm. The fuel used has a carbon content of 84.50 per cent and hydrogen content of 15.50 per cent by weight. The volumetric efliciency of the engine at Tuế of full thrott l at 4041 lan is 0.85 referred to 300 K and 1 batue ve engine is to pplied we of air coeflicient 0.95 when finning at 75% of full throttle. Calculate the throat diaweter of the vent uri if the air velocity at broat is not to exceed 200 1 rate of fuel flicien kg/s at the pressure drop at venturi o 1at. Discharge coellicient for the venturi is 0,8 and the area ratio of the venturi s 0.8. Take R for air as 0.287 kJ/kg K and for luel vapour is 0.09 kJ/kg K. а mixture iender the above operating conditions. vealculate the lution
