The absolute pressure inside a cylinder/piston device is 11.20 psi. What is the gauge/vacuum pressure? Assume standard atmospheric conditions.

A. -11.20 psi
B. 11.20 psi
C. 0 psi
D. 22.40 psi

Answer :

Final answer:

To find the gauge pressure from an absolute pressure of 11.20 psi, subtract the atmospheric pressure (14.7 psi) from the absolute pressure, resulting in a gauge pressure of -3.5 psi, indicating a vacuum relative to the atmosphere.

Explanation:

The question asks us to find the gauge pressure given an absolute pressure of 11.20 psi under standard atmospheric conditions. The standard atmospheric pressure at sea level is approximately 14.7 psi. Gauge pressure is the difference between absolute pressure and atmospheric pressure. Therefore, using the formula Pgauge = Pabs - Patm, where Pgauge is gauge pressure, Pabs is absolute pressure, and Patm is atmospheric pressure, we can perform the calculation:

Pgauge = 11.20 psi - 14.7 psi = -3.5 psi.

This value indicates that the gauge pressure is less than atmospheric pressure, suggesting a vacuum or suction rather than positive pressure. Hence, the correct answer is not listed among the options, but the closest incorrect option provided is a) -11.20 psi.
