A four cylinder four stroke engine has a cubic capacity of 1490 cc. it develops maximum power at 4200 rpm and air fuel ratio is 13:1. The air speed at venture is limited to 90 m/s. the volumetric efficiency of engine is 70%. Nozzle lip is 6 mm and atmospheric pressure and temperature are 1.013 bar and 293 K. An allowance is to be made for emulsion tube whose diameter should be taken as 1 /2.5 of venture diameter. Taking following data, calculate the diameter of venture and nozzle. Cda-0.85,Cdf=0.66 and density of fuel=740Kg/m3
