Flow in a pipeline with leakage

Leakage in pipelines has always been one of the main problems in pipelines transportation fluid. This fluid leakage can happened without any warning. The leaking of fluid in pipeline can give effects to the economic loss and environmental risk. Therefore, the early detection of leak is a main role i...
