EVAPORATION OF FREE WATER AND WATER BOUND WITH FOREST COMBUSTIBLES UNDER ISOTHERMAL CONDITIONSA. M. Grishin, A. N. Golovanov, and S. V. Rusakov UDC 533.6.011.6 Evaporation of free moisture and bound moisture in the form of droplets lying on a rough surface, and also moisture bound with forest combustibles (FC) of coniferous trees is studied experimentally. Empirical formulas are obtained for the rate of evaporation of water droplets under isothermal conditions as a function of the diameter of the droplets and the wall roughness. The laws governing evaporation of bound moisture of FCs and combined evaporation of free and bound moisture have been studied.
