#### The flow of gas in a cylindrical channel at a subsonic speed

... pressure), while the forces of gravity can be neglected. The boundary value problem is solves with the standard numerical method, the Mathcad in particular. The least squares method was used to find the empirical dependence of the heat nitrogen on the **temperature**. Third order polynomial approximation gives the average deviation from experimental data of less than 0.5 %. The paper also shows that with increase of the wall **temperature** of channel increases the required pressure at the inlet of the lance ...

#### The characteristics of the energy spectrum of mixture ratio and air **temperature** in the troposphere of the Antarctic

This article analyses the characteristics of the energy spectrum of mixture ratio and air **temperature** in the troposphere of the Antarctic obtained by Fourier analysis. Selected peaks of spectral density of mixing ratio and air **temperature** monthly averages are interpreted as annual and semi-annual fluctuations. The spectral density of random ...

... variations which delays an establishing of a seasonal water-exchange in shallows. Convective exchange flows within the entire shelf region in seasonal circle requires 4—7 weeks to reach a quasisteady state. Formation of a linear portion on the horizontal **temperature** profile can be used as an indicator of the approaching of the flow to the steady state. Flushing time for the shelf zone under steady-state condition is 30 days and is only slightly influenced by the slope length.
