At a dental appointment, the dentist will usually stick a tube in your mouth to suck up anyextra saliva. A sketch of this kind of suction device is shown below. The device works by flowing waterwith a velocity, vw = 0.15 m/s through a pipe with diameter, D = 2 cm. The water in the pipe thenmoves through a constriction with a smaller diameter, d = 1 cm, which drops the water pressure toan absolute value of 5290 Pa. The tube that is placed in your mouth is attached to the pipe at thecenter of the constriction. Assume your mouth is open to the atmosphere and saliva has the density ofwater (ρ = 1000 kg/m3). What is the maximum height, H, the pipe can be placed above you so yoursaliva will be sucked up the tube?
A cylinder that is h1=18.0 cm tall and open on top is filled with water. If a hole is made in the side of the cylinder, Δh=3.90 cm below the top level, how far x from the base of the cylinder will the stream land? Assume that the cylinder is large enough so that the level of the water in the cylinder does not drop significantly.
A uniform cross-sectional area U-tube is open to the atmosphere, is partially filled with mercury (density = 1.36 x104 g/cm3 ). Water is then poured into both arms. If the equilibrium configuration of the tube is as shown in Figure, with h2 = 1.00 cm, determine the value of h1.
ECIDO Consider a liquid (p = 1 kg/m³,) in a large bottle. It flows through a rather thin tube and come out of the tube at D. The cross-sectional area of the tube at C is c = 0.2 m², while all other parts have a cross-sectional area b = 0.1 m². The atmospheric pressure is Po= 105 Pascal, and the gravitational acceleration is g = 9.8 m/sec². Assume that the bottle is so large that the motion of the liquid at A is negligible.

Models of torpedoes are sometimes tested in a horizontal pipe of flowing water, much as a wind tunnel is used to test model airplanes. Consider a circular pipe of internal diameter 21 cm and a torpedo model aligned along the long axis of the pipe. The model has a 5.7 cm diameter and is to be tested with water flowing past it at 2.7 m/s. (a) With what speed must the water flow in the part of the pipe that is unconstricted by the model? (b) What will the pressure difference be between the constricted and unconstricted parts of the pipe?
