Problem: Heat transfer 11, a hundred pounds of haddock initially at 45 degrees is to be frozen to 20 degrees within three hours.
Given: 100 pounds times 0; 100 pounds times the 115 B2 per pound; 0.37 tons which is about 4 tenths of a ton answer choice B...
Approach: This is similar to a problem we saw earlier as well about freezing some pork with a added step where we have to not only find o...
Calc: It's actually got the same freezing point as pork, 28 degrees so I get some meats and fish or probably fairly similar.
Calc: We've got the freezing point which is 28 degrees and the specific heat capacity above the freezing point is 0.9 B2 per pound de...
Result: We'll be 13,438 B2 divided by three hours and that will give an answer in B2's per hour and one refrigeration ton is 12,000 B2's per hour so you ca...
