Pidstryhach of NAS of Ukraine popup.description2 The analysis and structuring data of the literature on the issue of water purification by industrial and household filters, on the structure and principles of multi-layer filters operation are carried out. The problem of the modes management for compressor stations is solved in order to ensure the gas main optimal operation mode on a wide scale of changes of gas transportation volumes. The model problem of gas withdrawing from underground gas storages by means of displacement it with water is developed. The mathematical model for calculation the parameters of underground gas storages during gas withdrawing is constructed. The obtained results are tested on the model problem. The mathematical model of the motion of fluids in flexible tubes is constructeded for different ways of outflow (inflow) of fluid along the tube - concentrated and uniform ones.
