Abstract

Due to the importance of the evaporation process and the need to control it in many chemical and production processes, this study was conducted to investigate the effect of magnetic field and salt on changes in water evaporation values at forced convection. In this study, to investigate the effect of salt and magnetic field variables on air temperature, water temperature, velocity, and relative humidity of the air, A laboratory device designed and measured the amount of evaporated water by inducing different conditions. The results of the present study showed that the magnetic field has a direct effect on the rate of change of evaporated water concentration so that increasing the strength of the magnetic field directly increases the amount of evaporation and these changes in the control group and group N at the probability level. 5% is significant so that the lowest evaporation rate belonged to the group with 0.5 Tesla and the highest evaporation rate belonged to the 1.5 Tesla group. Also, the results of the salt group showed that the amount of salt decreased the Evaporation values of water. The results showed that the magnetic field increased evaporation and the salt decreased evaporation.
