A substance containing 10 lb of moisture is placed in a sealed room, whose volume is 2000 cu ft and which when saturated can hold 0.015 lb of moisture per cubic foot. Initially the relative humidity of the air is 30 percent. If the substance to lose 80 percent of its moisture content? Assume the substance loses substance loses 4 lb of moisture in 1 hr, how much time is required for the sub- moisture at a rate that is proportional to its moisture content and to the difference between the moisture content of saturated air and the moisture content of the air
