[CO2 : Relationship between pressure and elevation ; Pressure Measurement]
1. The pressure is an unknown fluid at a depth of 1.22m is measured to be 12.55 kPa(gage).
Compute the specific gravity of the fluid.

2. The pressure at the bottom of a tank of propyl alcohol at 250C must be maintained at
52.75kPa(gage). What depth of alcohol should be maintained?
