Beer brewing begins with steeping grains in hot water, releasing the sugars inside. The sugar water is then heated to a boil and hops added. The hot temperature of the boil extracts oils from the hops and provides sanitation from unwanted bacteria. The whole mess is cooled down and once it is safe enough for the yeast to survive, they are added. The yeast converts the sugars to alcohol, and the oils from the hops provide many things including flavor and antibacterial benefits.
a. If 16.5 lbs of grain at 67 degrees F are added to 5 gals of hot water and the equilibrium temperature of the mixture is to be 154 degrees F, what must the initial temperature (strike temperature) of the hot water be? The specific heat of malt grains is about 0.44 times that of water. Also, assume no energy is lost during the time the system comes to equilibrium.
b. During the one-hour steeping stage, where the water and grain mixture started at 2 degrees the mixture only lost 2 degrees What was the average energy per time lost by the mixture.
c. Enhancement: For this week's enhancement l will provide you with a question. You might wonder how much did it cost to heat the 5 gallons of tap water initially at 110 degrees to the strike temperature? Assume the heating takes 47 minutes, electricity costs 15 not C per kilowatt-hour, and only 10% of energy is lost during heating.
