Final answer:
The maximum receiving temperature for TSC in degrees Fahrenheit, after conversion from the given maximum permissible Kelvin temperature of 390 K, is roughly 242.33°F, which is closest to the provided choice of 250°F (Option D).
Step-by-step explanation:
The question pertains to determining the maximum receiving temperature for TSC (Thermal Systems Components) in degrees Fahrenheit. By analyzing the given information that the maximum permissible temperature in Kelvin is Th = 390 K, we can convert this temperature to degrees Fahrenheit. The conversion formula from Kelvin to Fahrenheit is
. Using this formula, we get the maximum temperature as
, which roughly equals 242.33°F. Therefore, the maximum receiving temperature for TSC in degrees Fahrenheit is closest to 250°F, which corresponds to option D in the given choices.
