What is the theoretical time necessary to reduce the temperature of 40,000 pounds of onions (placed in a refrigerated container) from 75°F to a set point temperature of 46°F? (The specific heat of onions is 0.90 BTU/LB/°F. The trailer heat gain is 6,500 BTU/hr, with a properly operating refrigeration cooling capacity of 45,500 BTU/hr.)
