1.
In the hydraulic system shown in Figure 15-28, the piston on the left has a
diameter of 4.4 cm and a mass of 1.8 kg. The piston on the right has a diameter
of 12 cm and a mass of 3.2 kg. If the density of the fluid is 750 kg/m3, what is
the height difference h between the two pistons? [Answer: 1.2 m]
2.
A horizontal pipe contains water at a pressure of 110 kPa flowing with a speed
of 1.6 m/s. When the pipe narrows to one half of its original diameter, what are
the (a) the speed, (b) the pressure of the water? [Answer: a) 6.4 m/s b) 90800
Pa]
