Question

If you had to raise the temperature of 2000 lbs of aluminum needs to be raised from 75o F to 100o F, how many Btu will the equipment have to produce per hour?

Answer 1

The equipment needs to produce 10750 Btu per hour to raise the temperature of 2000 lbs of aluminum from 75°F to 100°F.

The specific heat capacity of aluminum is 0.215 Btu/lb°F. This means it takes 0.215 Btu to raise the temperature of 1 pound of aluminum by 1 degree Fahrenheit.

Calculating the total heat required (in Btu):

* Temperature difference = 100°F - 75°F = 25°F

* Total heat required = 2000 lbs * 0.215 Btu/lb°F * 25°F = 10750 Btu

Converting the total heat required to Btu per hour (assuming the equipment operates continuously for an hour):

Btu per hour = total heat / time = 10750 Btu / 1 hour = 10750 Btu/hour

Therefore, the equipment needs to produce 10750 Btu per hour to raise the temperature of 2000 lbs of aluminum from 75°F to 100°F.
