A 6.2-liter, V8, four-stroke cycle SI engine is designed to have a maximum speed of 6500 RPM. At this speed, volumetric efficiency is 88%. The engine is equipped with a four-barrel carburetor, each barrel having a discharge coefficient of The fuel used is gasoline at (density of gasoline).

Calculate: (a) Minimum throat diameter needed in each carburetor venturi. [cm]

(b) Fuel capillary tube diameter needed for each venturi throat if tube discharge coefficient CDc=0.85 and the capillary tube height differential is small. [mm]
