Example 3.5-2 Temperature Conversion
(a) A proton exchange membrane fuel cell operates at 80.0°C. Determine the temperature in
degrees Kelvin, Fahrenheit, and Rankine.
Strategy
We can use temperature conversion formulas to solve this problem.
Solution
Using the temperature conversion formulas we have:
T(K) = T(°C)+273.15 =
+273.15
T(K) =_K
T(°F) = 1.8T(°C)+32 = 1.8(_ )+32
T(°F) =
°F
T(R) = T(°F) +459.67 =
+459.67
T(R) =
R
(b) A solid oxide fuel cell operates at 1200°F. Determine the temperature in degrees Kelvin,
Celsius, and Rankine.
Strategy
We can use temperature conversion formulas to solve this problem.
Solution
Using the temperature conversion formulas we have:
T(R) = T(°F) +
T(R) =
R
T(°F) –
T(°C) =
T(°C) =
°C
T(K) = T(°C) +
T(K) =,
K.
