Abstract
The current algorithm for calculating mass flow rate in gas production and transportation systems via outlet pressure measurements is generalized to the case when the inner cross section of pipe changes with time and is also to be determined while solving the general problem. The algorithm is recommended for identification of gas hydrate formation in the above-mentioned systems.

We will set forth an algorithm for determining mass flow rate of gas from pressure measurements at the outlet, when cross-section varies along the length and in time due to the formation of hydrate layer
Summary
The formation and deposition of hydrates in pipelines is studied using quasi-stationary mathematical model [1,2,3,4,5,6,7,8]. Ambient temperature Te is replaced with equilibrium hydrate formation temperature Th. we will set forth an algorithm for determining mass flow rate of gas from pressure measurements at the outlet, when cross-section varies along the length and in time due to the formation (dissociating) of hydrate layer.
