A container of water has a cross-sectional area of A=0.1m2 . A piston sits top of the water (see be following figure). There is a spout located 0.15 m from the bottom of tank, open to the atmosphere, and a stream of water exits the spout. The cross sectional area of the spat is As=7.0104m2 . (a) What is the velocity of the water as it leaves the spout? (b) If the opening of the spout is located 1.5 m above the grand, how far from be pout does water hit the floor? Ignore friction and dissipative forces.
A certain hydraulic system is designed to exert a force 100 times as large as the put into it. (a) What must be the ratio of the area of the cylinder that is being controlled to area of the master cylinder? (b) What must be the ratio of their diameters? (c) By what factor is the distance through which the output force moves reduced relative to the distance through which input force moves? Assume no losses due to friction.
If a thermometer is allowed to come to equilibrium with the air, and a glass of water is not in equilibrium with the air, what will happen to the thermometer reading when it is placed in the water?
Water is shot nearly vertically upward in a decorative fountain and the steam observed to broaden as it rises. Conversely, a stream of water falling straight down from a faucet narrows. Explain why.
A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a 240-g rock 89.0 cm3 of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes' principle.)
What is the density of the unknown green fluid, of the blue fluid is water (density 1000 kg/m3) and the heights shown here are y = 3.40 cm and h = 7.00 cm?

A tank in the shape of a hemispherical shell has a diameter of 2m. Water escapes through a circularorifice 10 cm in diameter (C = 0.60) and located at the lowest point on the tank. Determine the timerequired to empty the tank assuming that it contains water amounting to half the volume of the tank.

The Bernoiulli effect can have important consequences for the design of buildings. For example, Wind can blow aorund a skyscraper at remarkably high speed, creating low pressure. The higher atmospheric pressure in the still air inside the buildings can cause windowspanes that fell many stories to the sidewalk below a) Suppose a horizontal wind blows with a speed of 11.2 M/s outside a large pabe of plate glass with dimensions 4.00m x 1.50m Assume the density of the air to be constant at 1.20kg/m3 The air inside the building is at atmospheric pressure. What is the total force exerted by air on the windowpane? b) What if a sencond skyscraper is built nearby, the airspeed can be especially high where wind passes through the narrow separation between the buildings. Solve part (a) again with a wind speed of 22.4m/s, twice as high

to the instantaneous depth of the water in the tank. 20 Water flows into a vertical cylindrical tank of cross-sectional area A ft at the rate of Q ft/min. At the same time, the water drains out under the influence of gravity through a hole of area a ft' in the base of the tank. If the water is initially h ft deep, find the instantaneous depth as a function of time. What is the limiting depth of the water as time increases indefinitely? 21 A vertical cylindrical tank of height h and radius R has a narrow crack of width w running vertically from top to bottom. If the tank is initially filled with water and allowed to drain through the crack under the influence of gravity, find the instantaneous depth of the water as a function of time. How long will it take the tank to empty? Hint: First imagine the crack to be a series of adjacent orifices, and integrate to find the total efflux from the crack in the infinites- imal time interval dt.
