Water flows at $1\mathrm{.}77$ cfs in a horizontal pipe of constant diameter $6.$ A pressure gauge at location $1$ records a pressure of $60$ psig and pressure at location $2$ records a pressure of $35$ psig. Location $2$ is $450$ ft downstream of location $1.$ What is the head loss between the two pressure gauges? What is the Darcy$-$Weisbach friction factor of the pipe? Specific weight of water is $62\mathrm{.}4$ lb$/$ft$3.1$ psig $=144$ psf$.$
