We have a two phase gas-liquid flow in a horizontal pipe. The length of the pipe is 200m, which is long enough to consider compressibility of gas phase. The initial liquid fluid velocity is 0.05m/s, and initial gas velocity is 5m/s. Below flow diagram seems to work well for our plant condition. Please explain how the flow regimes to evolve along the pipe Do you think splitting the pipe into few sections and running the calculations for each section will improve the pressure drop calculations? Explain your answer briefly in 3-4 sentences
