Question

The maximum safe air pressure of a tire is typically written on the tire itself. The label on a tire indicates that the maximum pressure is 30 psi (gage). Express this maximum pressure in kPa.

Answer 1

Answer:

206.85 kPa

Explanation:

Maximum pressure, p = 30 psi

To convert the pressure of psi units into Pa we use the following

1 psi = 6894.76 Pa

1 kPa = 1000 Pa

So, 1 psi = 6.895 kPa

So,

30 psi  = 30 x 6.895 kPa = 206.85 kPa

Thus, 30 psi is equal to 206.85 kPa

Answer 2

Answer:

206.841 Kpa.

Explanation:

In order to solve this we jus have to make a simple conversion, remember that 1 psi equals 6.8947 kpa so we use the next conversion:

$\frac{ 30 psi}{x kpa} =\frac{6,8947 kpa}{1 psi} \\x=30psi*6,8947kpa\\ x=206.841$

So the expression for 30 psi in Kpa would be 206.841
