KatRina [158]

Answer:

c) +2 to 0

the air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. How much pressure is this in pounds per square
Julli [10]

14.7lb/in²

Explanation:

This is a conversion problem from atm to pounds per square inch

Pressure is the combined force per unit area of substance on another.

Given pressure = 0.5atm

To solve this problem ;

Convert from atm to N/m² to pound per square inch

    1 atm = 101325N/m²

  0.5atm = 0.5 x 101325 = 50,662.5‬N/m²

now we need to convert to pound per square inch;

     1N  = 0.225lb

     1m = 39.37in

Solving;

 101325 Nx \frac{1}{m^{2} }  x \frac{0.225lb}{1N }  x \frac{m^{2} }{39.37in x 39.37in} = 14.7lb/in²
