Main Question or Discussion Point

Hello all,
Thank you for reading my topic. My client asked me to make calculation sheet for gas pipeline like the image below. Can someone help me to make this? (i'm new in this system, need to learn and study. So please help me)

How to calculate the required pressure at connection point if knowing pressure outlet, pipe diameter, length of gas (N2 – Nitrogen) pipe like image below? (Neglect pressure loss through fittings, valve and deferent high level of connection point and end point)

Thanks in advance

This was in your undergrad fluids book. It's in the chapter with the Moody diagram.

Hint 1: If the total pressure drop is more than a few percent, you will need to calculate in sections. There should be something about this in your fluids book.

Hint 2: You cannot ignore fittings and valves.

Hint 3: Some excellent resources in addition to your fluids book:
Compressed Air and Gas Data, by Ingersoll-Rand
Flow of Fluids Through Valves, Fittings, and Pipe, Crane Technical Paper 410

Hint 4: Use a spreadsheet.

The mass flow rate is 0.008 kg/sec sir
Based on that and the other data you presented, what is the Reynolds number for the flow?
