Answer :
The absolute pressure in the tire is (d) 400 kPa.
- To calculate the absolute pressure in a tire when you know both the gauge pressure and the atmospheric pressure, you can use the formula:
[tex]P_{abs} = P_g + P_{atm}[/tex]
- Where:
[tex]P_{abs}[/tex] is the absolute pressure.
[tex]P_g[/tex] is the gauge pressure.
[tex]P_{atm}[/tex] is the atmospheric pressure.
- In this problem, we have the following values:
Atmospheric pressure, [tex]P_{atm} = 100 \text{ kPa}[/tex]
Gauge pressure in the tire, [tex]P_g = 300 \text{ kPa}[/tex]
- Now, substituting the values into the formula:
[tex]P_{abs} = 300 \text{ kPa} + 100 \text{ kPa}[/tex]
[tex]P_{abs} = 400 \text{ kPa}[/tex]
