The venturi of a simple carburettor has a throat diameter 20 mm and the fuel orifice has a diameter of 1.12 mm. The level of petrol surface in the float chamber is 6 mm below the throat of venturi. The coefficient of discharge for venturi and fuel orifice are 0.85 and 0.78 respectively. Calculate (1) Air fuel ratio for the pressure drop of 0.08 bar. (ii) Petrol consumption in kg/hr.
