30PRACTICE PROBLEM
Consider a manometer formed with a U-shaped tube containing liquid of density 13.6 g/cm3 and connected to a frustum by the upper ends of the tube, as shown in the figure. Air flows inside the frustum at a rate of 900 cm3/s. Air is assumed to be an ideal fluid. Determine the difference in height between the two vertical columns of the manometer.
