We study the drying speed (mass transport) when drying textile materials in a drying room. The starting position is that the air condition in the drying room is +20°C and 50% RH. a) How does the drying speed change if the air condition was instead +15°C and 50% RH? Is it increasing, decreasing or unchanged? b) How does the drying speed change if the air condition was instead +20°C and 40% RH? Increases it, is it decreasing or is it unchanged? c) How does the drying speed change if we actively heat the textile material with infrared radiation (the air condition does not change)? Is it increasing, decreasing or unchanged? d) How does the drying speed change if we insert a fan in the room that only circulates the air in the room? Is it increasing, decreasing or unchanged? Justify your answers with a clear reasoning or simple calculation. We study the drying speed (mass transport) when drying textile materials in a drying room.
