A simple jet carburetor is required to supply 6 kg of air per minute and 0.45 kg of fuel of density 740 kg/m3. The air is initially at 1.013 bar and 27 C. Calculate the throat diameter of choke for a flow velocity of 92 m/s. Velocity coefficient is 0.8. If the pressure drop across the fuel metering orifice is 0.75 of that at the choke, calculate orifice diameter assuming Cd=0.60.
