If you have ever been swimming underwater, you know that one of the things you have to deal with is the weight of the water surrounding you. As you dive deeper, the total amount of water over you increases and so does its weight. Ocean water, because it contains salt, is heavier than fresh water. You can use the following models to find the amount of water pressure you will experience based on the depth of the water: . For fresh water: P = 62.4h For ocean water: P = 64.3h For both of these formulas, P is measured in pounds per square feet (that is, '0/42 ) and h is measured in feet below the surface of the water. 1. What is the water pressure in the ocean water at a depth of 12 feet? Use correct units in your answer. 2. Suppose a person is swimming in the ocean wearing diving suit consisting of scuba gear with air tanks. The diving gear will only let a person dive to a pressure of 1,286 /FAC. What is the domain and range for depth and pressure for this ocean water dive
