$5.)$ In your class textbook $(6^{th}$ Edition$)$ in Figure $11\mathrm{.}8(b)$ is seen a fire sprinkler system. The building shown in Figure $11\mathrm{.}8(b)$ is a remote building housing a telecom data center. As seen the sprinkler system is a drypipe system in case this remote building loses its heating source which are the computers$/$servers for the data center. Therefore the building does not typically need separate heating but in case of a power failure there would be no heating. The available water is well water. Therefore, in case of a fire, the sprinkler system goes from a "dry$-$pipe" state to a "wet$-$pipe" state and each sprinkler heads design flow is $35gpm.$ Your property insurance carrier tells you and your design team that a fire tank with a fire pump will need to be built to provide $30$ minutes of unimpeded water flow since the remote building is on well water. Fire tanks in standard sizes are available in $500-$gallon increments $($e$.$g$.12,000$ gallons, $12,500$ gallons, $13,000$ gallons, etc.$).10\%$ additional capacity in the fire tank is also necessary for water expansion in summer months. What size fire reservoir tank $($in gallons$)$ is required to meet these property insurance requirements?
