The pressure gauge on a compressed air tank reads 43.2 pounds per square inch (lb/in?). What is the

pressure in atmospheres (atm) ?

Answer: 2.94 atm

Explanation:

Given that,

Pressure in compressed air tank reads 43.2 pounds per square inch (lb/in)

Now, convert pressure to atmosphere (atm)

Recall that 1 atm = 14.695964 lb/in

so, let Z = 43.2 lb/in

To get the value of Z, cross multiply

43.2 lb/in x 1 atm = 14.695964 lb/in x Z

43.2 lb/in atm = 14.695964 lb/in x Z

Z = 43.2 lb/in atm / 14.695964 lb/in

Z = 2.94 atm

Thus, the pressure of the compressed air tank reads 2.94 atmosphere.
