Th = 527'C

efesiensi mula-mula dan terakhir?
Jwb:
efesiensi mula-mula:
e = 1 - Tl/Th × 100% = 1 - 127/527 × 100% = 1 - 0,24 × 100% = 0,76 × 100% = 76%
Maka efesiensi mula-mulanya 76%
efesiensi terakhir:
e = 1 - Tl/Th2 × 100% = 1 - 127/227 × 100% = 1 - 0,56 × 100% = 0,44 × 100% = 44%
Maka efesiensi terakhirnya 44%
