Problem 38P
A tire is filled with air at 15°C to a gauge pressure of 220 kPa. If the tire reaches a temperature of 38°C, what fraction of the original air must be removed if the original pressure of 220 kPa is to be maintained?
ANSWER:
Solution 38P:
Step 1 of 2:-
Here we have to find the fraction of original air that must be removed, if the original pressure of 220 kPa to be maintained.
The air inside the tyre has a temperature of: .
The gauge pressure is: .
The final temperature achieved is: .
