I need help calculating these for my CEA class, help please!

The water line is 15 years old.
The elevation at the lowest point of the tower’s water cavity is 872.81 ft.
The elevation at point of discharge 765 ft.
The pipe’s diameter is 6 in.
The pipe’s length is 3 miles.
The pipe is cast iron.
The pipe has seven 90-degree flanged elbows and one 45-degree flanged elbow.
The pipe’s flow rate is 100 gpm.
Calculate the static head at the point of discharge.
Calculate the head loss, including the losses for pipe fittings.
Calculate the dynamic head at the point of discharge .
Is the actual pressure sufficient for residential use? Should a pressure-reducing valve be installed?
