Abstract
The temperature distribution in concrete wall is calculated as an one-dimensional problem of heat conduction. The flux of heat from the wall surface is considered to be three components, i. e. solar radiation and heat transfer of convection and emission. The results are compared with the observed temperature in a model tank and three real water tanks. Fairly good agreement independent of place, date, direction and inclination confirm the propriety of the calculating process.
Some information on the highest surface temperature are obtained referring to the direction of the wall, the absorption coefficient of solar radiation and the correction factor to atmospheric transmissivity.
