You are using a food dehydrator to remove the water from grapes to make raisins. You have $2$ lbs of

grapes that you bought, that have $79\%$ percent moisture, by mass. The raisins have $11\%$ moisture. Your

food dehydrator is operating at a temperature of $140$ oF$.$ Assume the air leaving the food dehydrator is

saturated with water at $140$ oF$.$ The inlet air is at ambient conditions. What is the total volume of

entering air, in m$3,$ that would be needed to make the grapes, assuming the inlet air has no water in it
