What type of seal system is designed to restrict flow by requiring the fluid to pass through a series of ridges and intricate paths?
a. Lubrication
b. Labyrinth seal
c. Liquid buffered seal
d. Dry carbon rings
a. Incorrect. Lubrication is not a type of seal system.
b. Correct. A labyrinth seal is designed to restrict flow by requiring the fluid to pass through a series of ridges and intricate paths.
c. Incorrect. A liquid buffered seal is a close-fitting bushing in which a liquid is injected in order to seal the process from the atmosphere.
d. Incorrect. Dry carbon rings are a low-leakage type of seal that can be arranged with a buffer gas that separates the process gas from the atmosphere.

Recall that the function of a water tower is to create a desirable municipal water pressure for household use and other usage in a town. To achieve this purpose, water is stored in large quantities in elevated tanks. Also recall that the municipal water pressure may vary from town to town, but it generally falls somewhere between 50 and 80 lb/in2 (psi). In this assignment, use Excel to create a table that shows the relationship between the height of water above ground in the water tower and the water pressure in a pipe line located at the base of the water tower. The relationship is given by:
P = pgh where P = the water pressure at the base of the water tower (lb/ft2) p = the density of water, (rho) = 1.94 slugs/ft3 g = the acceleration due to gravity, g = 32.3 ft/s2 h = is the height of water above ground in feet (ft) Create a table that shows the water pressure in a pipe located at the base of the water tower as you vary the height of water in increments of 10 ft. Also plot water pressure vs. the height of water in feet. What should be the water level in the water tower to create 80 psi water pressure in a pipe at the base of the water tower?
