Fluid Mechanics (CEN 1013) Chapter 3: Static Fluid FWS 1 Tutorial 3 1) State the Pascal's law of pressure at a point in a fluid. 2) Most swimmers find the pressure at a depth of about 10 ft painful to ears. What is the gauge pressure at this depth? 3) How far below surface of water must one dive for the pressure to increase by one atmosphere? 4) At what depth below the free surface of oil having a density of 600 kg/m 3 will the pressure be equal to 1 bar? 5) What would the pressure in kN/m 2 be if the equivalent head is measured as 550 mm of : a. Mercury , S.G = 13.6 b. Water c. Oil, γ = 7.9 kN/m 3 d. A liquid of density 520 kg/m 3 ? 6) What will be (a) the gauge pressure (b) the absolute pressure of water at a depth of 12 m below the free surface? Figure 1 12 meter P atm P 1
