Pressurized pipe flow

A 15-kilometer-long pipe with a pipe diameter of one meter transports water at a speed of one meter per second. The pipe has a friction coefficient of 0.005. Calculate the frictional head loss?

Question

Please explain but also include the equation that was used to find each part

Oil (p = 888 kg/m³, µ = 0.8 kg/m.s) is to be transported in a smooth pipe having d' meter D = 5 cm and
length L = 40 m.
a. If the pressure at inlet was P₁ = 745 kN/m², and at exit was P₂ = 97 k' /m², calculate the flow rate
Q if:
i.
The pipe was horizontal
ii.
The pipe was inclined upwards by 15°
iii. The pipe was inclined downwards by 15°
You may assume that the flow in all three cases was laminar. Confirm, by calculating the
resulting Reynolds number, that this assumption is valid for each of the three cases.
b. If the flow rate in the horizontal pipe is increased such that Reynolds number Re = 105, calculate
the pressure drop that would occur between the pipe's inlet and outlet. Evaluate f from the
Blasius equation.
