Question

What is the absolute pressure of the air in your car's tires, in psi, when your pressure gauge indicates they are inflated to 35.0 psi

Answer 1

Answer:

342316.6 Pa

or

49.65 psi

Explanation:

Gauge pressure = 35 psi

The relation between the absolute pressure and the gauge pressure is given by

Absolute pressure = Gauge pressure + atmospheric pressure

1 atmospheric pressure = 1.01 x 10^5 Pa = 101000 Pa

First convert psi into Pascal

1 psi = 6894.76 Pa

So, 35 psi = 35 x 6894.76 = 241316.6 Pa

So,

Absolute pressure = 241316.6 + 101000 = 342316.6 Pa or 49.65 psi
