Question
The Venturi of a simple carburetor has a throat diameter of 25 mm and the coefficient of air flow is 0.87. The fuel orifice has a diameter of 1.35 mm and the coefficient of the fuel flow is 0.66. The petrol surface is 6 mm below the throat. Find (a) The air-fue ratio for a pressure drops of 0.07 N/m² when the nozzle tip is neglected. (b) The air-fuel ratio when the nozzle tip is taken into account (c) the minimum velocity of air or critical air velocity required to start the fuel flow when nozzle tip is provided. Take the density of air and fuel as 1.2 and 750 kg/m³ respectively.
