Water flows at a rate of 2.4f * t ^ 3 / s in an old, rusty 7.8-in.-diameter pipe that has a relative roughness of 0.010. It is proposed that by inserting a smooth plastic liner with an inside diameter of 7.0 in. into the old pipe as shown in the Figure the pressure drop per mile can be reduced. Is it true that the lined pipe can carry the required 2.4f * t ^ 3 / s at a lower pressure drop than in the old pipe? Support your answer with appropriate calculations.

I have attached the given moody diagram in this question, how do I complete this question accuractely?

(2) It is desired to deliver 60 m'/hr of water at 20°C through horizontal asphalted cast iron pipe. Estimate the pipe diameter d that will cause the pressure drop to be exactly 40 kPa per 100 m of pipe length. Take water density p Solve this problem iteratively using either Moody chart or the Colebrook equation. 998 kg/m and dynamic viscosity µ = 0.001 kg/(m.s).

I want step by step solution.

Question 3 Water flows through a 2-in.-diameter (5.08 cm) tube that suddenly contracts to 1 in. diameter (2.54 cm). The pressure drop across the contraction is 3.45 kPa.
