In present world the prime concern of a country is energy. Bangladesh, a developing country, is also facing the challenge to meet its energy demand. For the energy, Bangladesh mainly depends on its natural gas. Bangladesh has a gas reach province in the eastern part.Gas produced in Bangladesh is mainly dry gas, but some fields are also producing condensates. Natural gas is transported by pipeline, which is the most cost efficient way. With the edge of economy, gas transmission through pipeline brings some difficulties. Before transmitting the natural gas, condensates are separated in the gas field. In spite of the separation, some condensates are formed in the pipeline while transmitting gas. This leads to pipeline blocking, corrosion, reduction of heating value. In this study the fluid flow through Khadim-Debpur-Kumargaon (KDK) pipeline is analyzed, which is a part of the pipeline network operated by Jalalabad Gas Transmission and Distribution System Limited. To analyze the fluid flow through pipeline, pressure was calculated by single phase flow equations like Weymouth, Panhandle A and panhandle B. The pressure was also calculated using software Feket (Piper) and a statistical analysis of error calculation was done. The research focuses on the following points: i) the fluid flow pressure was under designed ii) a record of liquid formation in the pipeline should be kept iii) a chromatographic test on Kumargaon station should be done for improvement of the study iv) liquid formation gives hints of two phase flow in the pipeline, which demands more investigation.
