Chapter 5, Problem 23P

The demand for water during a fire is often the most important factor in the design of distribution storage tanks and pumps. For communities with populations less than 200,000, the demand Q (in gallons/mm) can be calculated by:

$Q=1020\sqrt{P}\left(1-0.01\sqrt{p}\right)$

whereP is the population in thousands. Plot the water demand Q as a function of the population P (in thousands) for $0\le P\le 200$ . Label the axes and provide a title for the plot.
