What heat-transfer rate equals one ton of cooling?
Correct Answer
C) 12,000 Btu/h
One ton of cooling equals 12,000 Btu/h.
Why This Is the Correct Answer
One ton of cooling equals 12,000 Btu/h.
Why the Other Options Are Wrong
Option A: 3,412 Btu/h
Choice A (3,412 Btu/h) is rejected because 3,412 Btu/h is a different published number than the cited Cooling ton Btu rate value; Cooling capacity conversion supports 12,000 Btu/h. The cited answer is 12,000 Btu/h.
Option B: 10,000 Btu/h
In mechanical and plumbing, 10,000 Btu/h is the wrong selection for Cooling ton Btu rate: 10,000 Btu/h is a different published number than the cited Cooling ton Btu rate value; Cooling capacity conversion supports 12,000 Btu/h.
Option D: 1,000 Btu/h
Choice D gives 1,000 Btu/h. Its specific error: 1,000 Btu/h is a different published number than the cited Cooling ton Btu rate value; Cooling capacity conversion supports 12,000 Btu/h. The accepted answer is 12,000 Btu/h.
Memory Technique
File cooling ton Btu rate under a field note: condition first, number or duty second, answer 12,000 Btu/h.
Reference Hint
