Td X = 90⁰ Tb X = -30⁰ Td C = 100 Tb X = 0⁰ T X = 60⁰X T C = ......................?
Penyelesaian :
Td X - T X Td C - T C __________ = ____________ Td X - Tb X Td C - TbC
90 - 60 100 - T C ________ = ____________ 90 - (-30) 100 - 0
30 100 - T C ____ = _______ 120 100
3000 = 120 (100 - T C) 3000 = 12000 - 120T C 120T C = 9000 T C = 75⁰C
Tb X = -30⁰
Td C = 100
Tb X = 0⁰
T X = 60⁰X
T C = ......................?
Penyelesaian :
Td X - T X Td C - T C
__________ = ____________
Td X - Tb X Td C - TbC
90 - 60 100 - T C
________ = ____________
90 - (-30) 100 - 0
30 100 - T C
____ = _______
120 100
3000 = 120 (100 - T C)
3000 = 12000 - 120T C
120T C = 9000
T C = 75⁰C
Jadi, suhu 60⁰X akan sama dengan suhu 75⁰C
