Please help me with this fluid mechanics question! Thank you!! :) A 1967 Harley-Davidson Shovelhead motorcycle uses a ventruri-carburetor to mix air and fuel for combustion. The venturi reduces the pressure to draw fuel from a reservoir chamber and to mix with the airstream as shown in the figure. The energy loss of the metering line is given by hL= (K*V^2)/2where K = 6.0 and V is the fuel velocity in the metering line. Assume that the air is an ideal fluid (68°F). Calculate the mass flux of air and the mass flux of fuel. Hint: Assume the air intake velocity is negligible.
