The sketch for Problem 2.22 shows a compartment divided into two sections a and b. The ambient barometric pressure reading is 28.0 inches of mercury (absolute). Gage A reads 5 kPa and gage B reads 150 kPa. Determine the reading of gage C and convert this reading to an absolute value.

Problem 2.22 

The accompanying sketch shows a compartment divided into two sections a and b. The ambient barometric pressure reading is 30.0 inches of mercury (absolute). Gage C reads 620,528 Pa and gage B reads 275,790 Pa. Determine the reading of gage A and convert this reading to an absolute value.
