On a cold, 5°F day, the nosewheel tire of a Learjet, having an internal volume of 1000. in3 is inflated to 30 psi (i. e., 30 lb/in2) above the ambient pressure of 14.7 psi. Calculate the weight (in pounds) and specific volume of the air in the tire. (Be careful of units here--we usually use feet, not inches, with imperial units in this course, and you need to work with absolute temperatures.)

The weight in (pounds ) is

The specific volume is

Explanation:

From the question we are told that

The temperature is

The volume is

The initial absolute pressure is

Generally from ideal gas equation we have

Here m is the weight nose wheel tire in pounds

R is the gas constant of air with value

So

=>

Converting to pounds

Form this equation specific volume is

=>
