2. Calculate the required pipe size for a gas-liquid stream, using the homogeneous flow model. Consider 20% margin. Standard schedule 80 steel pipe is required for this service. Pressure drop must be within 1520kPa per 100m. The line operates at 300kPag and 80C where local atmospheric pressure is 89 kPaa. The stream consists of 8Am3/h of oil with a specific gravity of 0.82 and viscosity of 48cP, water at a rate of 2,800Am3/h with a specific gravity of 1 and viscosity of 0.35cP, as well as 17,000 Sm3/d (dry basis) produced gas with an average molecular weight of 23 , viscosity of 0.012cP, and compressibility factor of 1 (assume for both dry and wet gas). Commercial steel pipe has a surface roughness of 0.046mm when clean. Molecular weight of water is 18.02. Standard conditions are 101.325kPaa and 15C. Use the pressure drop formula from Crane Publication 410M,1977: P=62530d5fLW2Re=354dW
