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.
