Problem
A vacuum chamber used for physics demonstrations is evacuated until the absolute pressure inside the chamber reaches 15kPa. The chamber is located in a laboratory where the atmospheric pressure on that particular day is 101kPa.
(a) Determine the gauge pressure inside the chamber once the desired vacuum level has been reached.
(b) A sensor mounted on the chamber door is designed to display pressure relative to the ambient laboratory air. What numerical reading (including the appropriate sign) should the sensor show under these conditions?
