1. You dive 5 m down in the ocean. What isthe absolute pressure there? Assume your weight is 170pounds.
2.A 2.5 m tall steel cylinder has a cross sectional area of 1.5m2. At the bottom with a height of 0.5 m is liquidwater on top of which is a 1 m high layer of gasoline. Thegasoline surface is exposed to atmospheric air at 101 kPa. What is the highest pressure in the water?
3.Water at 120 celcius with a quality of 25 % has its temperature raised 20 celcius in a constant volume process. What is the new quality and pressure? Draw P-v and T-s diagrams.
4.A pressurized steel bottle is charged with 5 kg of oxygen gas and 7 kg of nitrogen gas. How many kmoles are in the bottle?
5.A laboratory room keeps a vacuum of 0.1 kPa. What net force does that put the door of size 2 m by 1m?
