PPLEASE HELP ASAP! Show all work and explain, Im very confused

In the supply system $)=(0\mathrm{.}89cfs$ shown in the figure, the pressure required at the delivery end is $65.$ Consider the entrance and exit losses and a water temperature of $70F,$ determine: The pumping head and The power delivered by the pump $($efficiency $0\mathrm{.}62)$

Solution:

Velocity of the flow in pipe is $v=\frac{t}{s}$

Major loss $h_f$

Darcy$-$Weisback equation method:

Roughness of commercial steel is $e=2{10}^{-4}ft$;

At $70F,$ kinematic viscosity of water is $v=1\mathrm{.}06{10}^{-5}f\frac{t^2}{s}$;

Relative roughness is $=$

Reynolds number is $Re={10}^5$;

From Moody diagram, frictional factor $f$

Thus $h_f=ft.$

Hazen$-$Williams equation $)=(105$ :

$h_1=ft$

Chezy$-$Manning equation $(n=0\mathrm{.}011)$:

t$.h_{+}$

Minor loss for $$ hydraulic fittings

$h_m=$

Energy equation for the purnp head: $HH=$

Power defivered by the pump Wp$.$
