By how many degrees is the overboard temperature higher than the injection temperature?

Explanation:
The difference is found by subtracting the injection temperature from the overboard temperature. The overboard reading is higher, so you’re measuring a positive rise from the injection point to the overboard point. In this case, the two readings differ by 10°F, so the overboard temperature is 10°F higher than the injection temperature. For example, if the injection temperature were 300°F, the overboard temperature would be 310°F, giving a 10°F difference.
