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.

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 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.

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.

Suppose you have a 8.8 cm diameter fire hose with a 3.4 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.)
