Question

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 piles that deliver the water to customers. The drawing shows a spherical reservoir that contains 4.42 x 10^5 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 fhe diameter of the delivery pipes.

Answer 1

Volume, V = (4/3) pi r^3

4.42 x 10^5/1000 = (4/3) pi x r^3

Radius, r = 4.73 m

A)

Pressure, P = pgh

P = 1000 x 9.8 x (2 x 4.73 + 15) = 2.40 x 10^5 Pa

B)

Pressure, P = (15 - 7.3 + 2 x 4.73) x 1000 x 9.8 = 1.68 x 10^5 Pa
