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 41.0 lb/in.2 . Convert 41.0 lb/in.2 to its equivalent in atmospheres.

Answer 1

Step 1

Information needed to convert lb/in^2 to atm:

1 lb/in^2 = 0.0680 atm

----------

Step 2

Procedure:

41.0 lb/in^2 x (0.0680 atm/1lb/in^2) = 2.79 atm

Answer: 2.79 atm
