The transportation of gas through pipelines is complex process and possess risks of leakage. The design and supply chain of gas pipelines should be properly done in order to meet demands and reduce risks. The objective of current research is to investigate the effect of external air velocity on exposure zone of methane air from gas pipeline leakage. The CAD modelling of exposure zone as computational domain is developed in Creo parametric software and CFD analysis is conducted using ANSYS v21 software. The results have an increase in exposure zone with increase in external air velocity. The methane exposure zone for 5m/s is found to be .14m whereas for external air velocity of 10m/s the exposure zone of .17m is found.
