Use the following data for solving problems:
Viscosity of methane () = 0.011×10-³ kg m-¹ s-1
Molecular weight (M) = 16.0 kg kmol-¹
Universal gas constant (R) = 8314 J kmol-¹ K-¹
1. 50 kg s-1 of a natural gas (essentially methane) is required to flow through a 0.6
m diameter and 4 km long pipeline (relative roughness = 0.0014) at a constant
temperature of 20 °C, and to discharge at a pressure of 5 atm. What upstream
pressure will be required to maintain the flow rate?
[Ans. 9.32 atm]
