In the water tower system shown below, and the minimum pipe diameter needed to make sure that the water pressure at the consumer's house under a maximum consumption rate of $1200$ gal$/$hr is at least $80$ KPa. Ignore the minor head losses and assume that the pipe is made of PVC and is relatively new. For the tower's elevation and the pipe's length, look at the provided table. Hint: Use the Hazen$-$Williams equation. $2)$ In the water tower system shown below, and the minimum pipe diameter needed to make sure that the water pressure at the consumer's house under a maximum consumption rate of $1200\backslash (\backslash$mathrm$\{$gal$\}/\backslash$mathrm$\{$hr$\}\backslash )$ is at least $80$ KPa $.$ Ignore the minor head losses and assume that the pipe is made of PVC and is relatively new.
