Question

The National Center for Atmospheric Research has a laboratory located on the Table Mesa in south Boulder. THis lab is located high above most of Boulder. Water to the lab is supplied from a big green water tank, which is located on a ridge 300m west of the lab. The bottom of the tank is 60m higher than the lab.
1. Why does NCAR get its water supply from a tank rather than the wate mains pipe like the rest of us in Boulder?
a. Outside range of city water mains-it is getting water supply from a spring that feeds the tank
b Tank ensures a steady and decently high water pressure in a building that sits way higher than the rest of town
c. Historical reasons-if NCAR were built today it would get its supply straight from the water mains in town
d. Tank minimizes the water pressure at NCAR preventing pipes from bursting
e. none of the above

Explanation / Answer

b) Tank ensures a steady and decently high water pressure in a building that sits way higher than the rest of town.

Powered motors would be required if water mains pipe were to be used.
