Most towns use a water tower to store water and provide pressure in the pipes that deliver water to customers. The figure below shows a spherical water tank that holds 5.40 10^5 kg of water when full. Note that the tank is vented to the atmosphere at the top and that the pipe delivering water to customer Smith is a height h = 8.25 m above the level of the pipe delivering water to customer Jones. Determine the gauge pressure of the water at the faucet of each house when the tank is full.

Water flows from a fire truck through a hose that is 11.7 cm in diameter and has a nozzle that is 2.0 cm in diameter. The firemen stand on a hill 3.0 m above the level of the truck. When the water leaves the nozzle, it has a speed of 20.0 m/s. 1) Determine the minimum gauge pressure in the truck's water tank. (Express your answer to two significant figures.) Pa Submit

Problem 3: Water flows through a horizontal cylindrical pipe from a smaller-diameter region to a larger-diameter region. At point A, where the pipe's diameter is 3.5 cm, the water's speed at 25.0 m/s. At point B, the pipe's diameter is 7.0 cm. (a) What is the water's speed at point B? (b) What is the pressure difference between points A and B? Which point has the greater pressure?

A pipe with an inner diameter of 2.00 cm is being used to deliver water at an absolute pressure of 4.00 X 105Pa, with constant flow speed of 1.50 m/s. It is then connected to another pipe with a diameter of 1.00 cm placed in the 2nd floor located 5.00m above the first pipe. What is the absolute pressure at the pipe in the 2nd floor?

Suppose you have a 8.8 cm diameter fire hose with a 3.6 cm diameter nozzle. a) Calculate the pressure drop due to the Bernoulli effect as water enters the nozzle from the hose at the rate of 40.0 L/s. Take 1.00 × 103 kg/m3 for the density of the water. b) To what maximum height, in meters, above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.

A mix of mostly high fructose corn syrup and other special ingredients, with a viscosity of 0.157 Pa · s, is carried through a pipe in a candy factory.  That pipe is laid out horizontally, has a length of 54.2 m, a radius of 0.936 cm and a volume flow rate of 6.1 x10-5 m3/s.  At the output end of the pipe the pressure is atmospheric pressure. What is the absolute pressure at the input end?

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 6.54 x 105 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.

Water is flowing smoothly through a closed-pipe system. At one point, the speed of the water is 3.0 m/s, while at another point 1.0 m higher, the speed is 4.0 m/s. If the pressure is 20 kPa at the lower point, what is the pressure at the upper point? What would the pressure at the upper point be if the water were to stop flowing and the pressure at the lower point were 18 kPa?

A liquid-filled tube called a manometer can be used to measure the pressure inside a container by comparing it to the atmospheric pressure and measuring the height of the liquid. Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 12.2 cm higher than on the side connected to the balloon.    a. Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3.  b. Find the absolute pressure in the balloon, in units of Pa.

Water pressurized to 6.5 × 10° Pa is flowing at 5.0 m/s in a pipe which contracts to 1/3 its former area. What is the pressure and velocity of the water after the contraction? Select one: O A. 2.5 x 10° Pa, 15.0 m/s O B. 4.5 × 10 Pa, 1.5 m/s O C. 3.0 × 10° Pa, 10 m/s O D. 3.0 × 10° Pa, 15.0 m/s O E. 5.5 × 10° Pa, 15.0 m/s
