Extracted text: TThe venturi of a simple carburetor has a throat diar the coefficient of flow is 0.8. The fuel orifice has a and the coefflicient of fuel flow is 0.65. The gasolin surface is 5 mm below the throat, calculate * of 20 mm and er of 1.14 mm when the nozzle (i) the air-fuel ratio for a pressure drop of 0.0. tip is ne arted (ii) the aiaeDW atio when the nozzle tip is taken into account (iii) the minimum velocity of air or critical air velocity requi red to start the fuel flow when the nozzle tip is provided. Assume the density of air and fuel as 1.20 and 750 kg/m respectively.
