Question

The pressure in car tires is often measured in pounds per square inch (lb/in.2), with the recommended pressure being in the range of 25 to 45 lb/in.2. Suppose a tire has a pressure of 34.5 lb/in.2 . Convert 34.5 lb/in.2 to its equivalent in atmospheres. Express the pressure numerically in atmospheres.

Answer 1

1 atmosphere = 14.7 lb/in

So to convert lb/in to atmosphere, just divide by 14.7.

28.5 / 14.7 = 1.94 atmospheres.

Answer 2

A tire with a pressure of 34.5 lb/in², has a pressure of 2.35 atm.

Let's suppose a tire has a pressure of 34.5 lb/in². This is the given data.

We want to convert 34.5 lb/in² to atm. The required conversion factor is 1 atm = 14.7 lb/in².

The pressure of the tire, in atm, is:

$34.5 lb/in^{2} \times \frac{1 atm}{14.7 lb/in^{2}} = 2.35 atm$

A tire with a pressure of 34.5 lb/in², has a pressure of 2.35 atm.
