  1. Pressure = Force/Area P = F/A P = lb/in2 P = N/m2

  2. Pressure = Weight/Area P = W/A P = N/m2 W P = lb/in2 Suppose Weight = 100 lb and Area = 10 in2 Suppose Weight = 100 lb and Area = 1 in2 Suppose Weight = 100 lb and Area = 100 in2 A P = W/A P = W/A P = W/A P = 100lb/10in2 P = 100lb/1in2 P = 100lb/100in2 P = 10lb/in2 P = 100lb/in2 P = 1lb/in2

  3. P = W/A P = W/A P = 100lb/1in2 P = 100lb/100in2 P = 100lb/in2 P = 1lb/in2

  4. P = F/A F F = 100lb A = .01in2 P = 100lb/.01in2 P = 10,000lb/in2 AAA A

  5. Depth Pressure depends on depth only. Pressure = Weight Density x Depth

  6. P = F/A 0 ft P = 15 lb/in2 = 1 atmosphere P = 30 lb/in2 = 2 atmospheres 32 ft 64 ft P = 45 lb/in2 = 3 atmospheres

  7. P = F/A P1 P3> P2> P1 P2 P3

  8. An object displaces an amount of fluid equal in weight to its loss of weight in that fluid. This is called Archimedes Principle

  9. W3 W2 W1 W3 = weight of object in air = 3 An object displaces an amount of fluid equal in weight to its loss of weight in that fluid. W1 = weight of object in water = 1 W2 = weight water displaced = 2 W2 – W1 = W2 3 -1 = 2 This is called Archimedes Principle
