The venturi is being used as a suction device to introduce petrol into an air stream, as in a carburettor in a car engine. using continuity and bernoulli’s equation. the diameter of the air duct at the throat of the venturi is 15 mm, expanding to 30 mm at the exit into the atmosphere. the suction pipe exits to the air flow 150mm above the surface of the liquid reservoir. the liquid fuel and air have densities of 800kg/m3 and1.2kg/m3 .assume the air to be an ideal fluid. state and justify any other assumptions made. 1)- draw venturi meter, showing the inlet and outlet of the fluid. 2)- estimate the volume flow rate q of air required before liquid is sucked into the airstream. 3)- list systematically the hydrostatic pressure laws.
