Gas undergoes changes in pressure and temperature during the distribution process in the pipeline. Due to these changes, there is a condensation process occurred inside the pipeline. This condensation process somehow can affect the amount of pressure drops. Moreover, the amount of pressure drops depends on two-phase friction factor, two-phase density, total mass flux rate, mixture velocity, seperfisial gas velocity (physical properties of fluid) etc. This final project is conducted to determine the pressure and temperature drop in two-phase system of condensated gas by calculating the physical properties of fluid using a compositional approach. The completion of compositional model is executed by using numerical approach, while <br /> <br /> <br /> <br /> <br /> <br /> <br /> the pressure drop is done by using Runge-Kutta 4th order method. Computation results show the influence of physical properties of gas over the occurring pressure and temperature drops.
