2. Pressure: 38 bar

3. Gas temperature: 35 ° C

4. Mass flow rate: 24 kg / h

5. Internal diameter of pipe: 9 mm

6. Roughness of the pipe: [url removed, login to view] (steel AISI304)

7. Pipe wall temperature: 40 ° C

(any needed parameters can be added)

The calculation must be made in Mathcad or Excel
