In the contracted conduit shown, liquid methanol (at 68 F ) is sucked from an open reservoir into an airstream. The approach section has a diameter D= 4-in while the contracted section has a diameter of d= 2-in. The surface of the methanol reservoir is at an elevation H= 1.8 ft below the contracted air section, and the airflow rate is such that the air speed is V= 110 ft/s in the smaller diameter pipe (it should not be assumed that the airstream discharges into the atmosphere)
