You purchased a ton of wet hops (75% water by weight), and need to dry them to 10% water by weight.
How much energy is required to drive off the water?
How much wood (i.e., mass) do you need to burn (if you ran a 1900's Oast -- hop kiln) in order to drive off the water? You may assume 100% energy efficiency, and the heat of combustion of wood to be Hc = 16,300 kJ/kg
