$5\mathrm{.}3\mathrm{.}23$ WP Water flows by gravity from one lake to another as sketched in Fig. P$5\mathrm{.}3\mathrm{.}23$ at the steady rate of $80$ gpm$.$ What is the loss in available energy associated with this flow? If this same amount of loss is associated with pumping the fluid from the lower lake to the higher one at the same flowrate, estimate the amount of pumping power required.
