Physics

Before Fuel Injection. Some automobile engines (mainlyolder ones) use a carburetor to turn the liquid fuel into vapor andmix it with air for combustion. The basic principle of carburetionis shown in Figure P10.82. A piston moves down in the cylinderthereby moving air from the outside through the carburetor by wayof an air filter and into the carburetor. The filtered air entersfrom the left of Figure P10.82 and moves into the main intake, atube of diameter 4.2 cm, with velocity v = 10 m/s. The air mustpass through a region of the intake that has a smaller diameter.Determine what diameter would be needed cause a change in pressuresuch that fuel from the reservoir is pulled into the airflow. Thesurface of the fuel in the reservoir is h = 37 cm below the bottomof the intake and the density of the fuel is 0.45 that of water.Use 1000 kg/m^3 for the density of water and 1.29 kg/m^3 for thedensity of air
