1. The atmospheric pressure at an elevation of 300 m was 100 kPa. when the temperature was 20°C. If the temperature varies at the rate of – 0.006° C/m, determine the pressure at height of 1500 m.

2. The bourden type pressure gauge in the oxygen cylinder of a deep sea diver when he is at a depth of 50 m reads 500 kPa. Determine the pressure of oxygen above atmospheric pressure. Assume sea water density is constant and is 1006 kg/m³.
