A water tower is a familiar sight in many towns. The purpose of such a tower is to provide storage capacity and to provide sufficient pressure in the pipes that deliver the water to customers. The drawing shows a spherical reservoir that contains 3.09 x 10 kg of water when full. The reservoir is vented to the atmosphere at the top. For a full reservoir, find the gauge pressure that the water has at the faucet in (a) house A and (b) house B. Ignore the diameter of the delivery pipes. Vent 150m Faicet 7.30m Tacet

Problem 3: A person walks around in high-heeled shoes. Their weight is momentarily placed on one heel which has an area of 1.5 cm². If their mass is 60 kg, what is the pressure exerted by their heel on the floor in pascals?

Question 7 of 18 You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 × 10³ kg/m³, fills the lower portion of the container to a depth of 0.200 m. The fluid that is floating on top of the water is 0.307 m deep. If the absolute pressure on the bottom of the container is 1.049 × 10° Pa, what is the density, pi, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po = 1.013 x 10° Pa. Pi = kg/m3

A stick of butter has dimensions 130 mm × 30 mm × 30 mm and density pt = 870 kg/m³. It is placed in a bowl of cool water and floats with its long side oriented horizontally. What volume of butter is submerged? (As always, drawing a force diagram is a great first step.) What is the smallest amount of mass m you must place on top so that the butter becomes fully submerged? Suppose that the stick is balanced very delicately so that it floats with its long side oriented vertically. How would this change your answers above?

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe has a diameter of 17.0 cm. The lower end of the pipe has a diameter of 6.80 cm. The flow rate of the water in the pipe is 0.0500 .What is the speed of the water at the lower end of the pipe?

While taking a shower, you notice that the shower head is made up of 44 small round openings, each with a radius of 2.00 mm. You also determine that it takes 5.00 s for the shower to completely fill a 1.00-liter container you hold in the water stream. The water for the shower is pumped by a pump that is 5.50 m below the level of the shower head. The pump maintains an absolute pressure of 1.50 atm. Use g = 10 m/s2, and assume that 1 atmosphere is 1.0  105 Pa. (a) At what speed does the water emerge from the shower head? (b) What is the speed of the water in the pipe connected to the pump? (c) What is the cross-sectional area of the pipe connected to the pump?

A water pipe having a 2.31 cm inside diameter carries water into the basement of a house at a speed of 0.945 m/s and a pressure of 187 kPa. If the pipe tapers to 1.03 cm and rises to the second floor 7.30 m above the input point, what are the (a) speed and (b) water pressure at the second floor? (a) Number i Units (b) Number i Units

On another planet that you are exploring, a large tank is open to the atmosphere and contains ethanol. A horizontal pipe of cross-sectional area 7.0×10−4m27.0×10−4m2 has one end inserted into the tank just above the bottom of the tank. The other end of the pipe is open to the atmosphere. The viscosity of the ethanol can be neglected. You measure the volume flow rate of the ethanol from the tank as a function of the depth hh of the ethanol in the tank. If you graph the volume flow rate squared as a function of hh, your data lie close to a straight line that has slope 2.09×10−5m5/s22.09×10−5m5/s2.   What is the value of gg, the acceleration of a free-falling object at the surface of the planet? Express your answer with the appropriate units.

(Figure 1) shows a container with a cross section area of 15 cm² in which a layer of water floats on top of a layer of mercury. A 1.0 kg wood block with a cross-section area of 10 cm² floats on the water. The water depth, measured from the bottom of the block, is 25 cm. A pressure gauge at the bottom of the container reads 20 kPa. Figure 1.0 kg 25 cm h 10 cm² 15 cm² 1 of 1 > Part A = What is the depth dm of the mercury?
