The venturi of a simple carburettor has a throat diameter of 20 mm and the coefficient of flow is 0.8. The fuel orifice has a diameter of 1.14 mm and the coefficient of fuel flow is 0.65. The density of air and fuel to be 1.20 kg/m and 750 kg/m. When the nozzle tip is neglected the air fuel ratio for a pressure drop of 0.8 bar is 3 1) 15.15 2) 13.1 3) 12.5 4) 16,0

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
