The solution is obtained through explicit single-step integration scheme (Runge-Kutta-Fehlberg method) — both for single-section and multisection dams. The integration scheme is modified taking into consideration the special conditions formulated to be imposed on the sections.

In particular, if the equilibrium state corresponds to the condition of no supply of heat, then: 0 < n< k, k— ratio of specific heats. For the existence of the gap in the maximum mass flow rate it is necessary that: n=gL/RT0, where L— the height of the slit, T0 - temperature at ground level. Polytropic index n is related to the intensity of heat transfer from hot wall to the flow: with increasing intensity of heat transfer n →+0. 532(075.8) FREE-CONVECTIVE FLOW NATURAL DRAFT AIR FLOW IN VERTICAL CHANNELS HEAT TRANSFER ADIABATIC EQUILIBRIUM https://engtech.spbstu.ru/article/2012.77.48/

Non-load-bearing brick walls and reinforce–concrete columns lean on concrete foundation slab. The reasons of crack origin and development in brickwork are exposed. The main reason is uneven deformations of foundation slab at the different filling of reservoirs. The results of instrumental reserches and model experiment are confirmed by calculations. Offered and realised measures of constructions strengthening, after that cracks development was halted. 621.21.9 BUILDING DESIGNS TECHNICAL INSPECTION FOUNDATION SLAB CONCRETE COLUMNS STEEL TANKS, BRICKLAYING CRACKS TOOL RESEARCHES NATURAL EXPERIMENT TESTING CALCULATIONS https://engtech.spbstu.ru/article/2012.77.49/
