13 An automobile carburettor having its flost chamber vented to the atmosphere is testedat sea level conditions in the factory without air cleaner. The main metering systemof this carburettor is found to yield a fuel-air ratio of 0.065. The venturi throat pressureis 0.85 bar. The carburettor is now installed in an automobile and air cleaner is placedon the inlet to carburettor. The air flow rate with or without air filter is 230 kg/hr. Thepressure drop through the filter is found to be 0.035 bar at sea level conditions.Issuming 7. nand orifice cocfficient to be constant calculate:The venturi throat pressure with air cleaner.
