A fresh water pond that is 14.7 m deep is contained on one side by a cliff. The water has eroded a nearly horizontal "tube" through a bed of limestone, which allows the water to emerge on the other side of the cliff. If the "tube" has a diameter of 4.07 cm,...
The following tube has dimensions d1=1.16 cm and d2=3.60 mm. Air (density = 1.28 kg/m3) flows through the tube at a rate of 1100.0 cm3/s. Assume that air is an ideal fluid. What is the height h of mercury (density = 13600.0 kg/m3) in the right side of the U tube?
