Annotation | The one-dimensional nonstationary problem of temperature distribution in the mechanical system «pipeline – pressure sensor» is considered. A numerical and analytical method of solution based on the Galerkin method is proposed. The solution of the problem is reduced to integration of a system of linear ordinary differential equations of the first order with constant coefficients. In the case when the temperature at the pipeline inlet is constant, the analytical solution of the problem is constructed using the method of separation of variables. |

Keywords | heat exchange, pipeline, pressure sensor, differential equations, Galerkin method, method of separation of variables. |
