Fig. P. 2.31 Problem 2.32 For the inverted manometer of Fig. P2.32, all fluids are at 20°C. If pB-pA=97 kPa, what must the height H be in cm Fig P.2.32

Problem 2.33 In Fig. P2.33 the pressure at point A is 25 lbf/in2. All fluids are at 20°C. What is the air pressure in the closed chamber B, in Pa Fig. P.2.33 Problem 2.35 Water flows upward in a pipe slanted at 30°, as in Fig.P2.35. The mercury manometer reads h=12 cm. Both fluids are at 20°C. What is the pressure difference p1-p2 in the pipe

Fig.P.2.35 Problem 2.36 In Fig. P2.36 both the tank in addition to the tube are open to the atmosphere. If L 2.13 m, what is the angle of tilt of the tube Fig. P.2.36

Problem 2.51 Gate AB in Fig. P2.51 is 1.2 m long in addition to 0.8 m into the paper. Neglecting atmospheric pressure, compute the as long as ce F on the gate in addition to its center-of-pressure position X. Fig. P. 2.51 Problem 2.53 Panel ABC in the slanted side of a water tank is an isosceles triangle with the vertex at A in addition to the base BC=2 m, as in Fig. P2.53. Find the water as long as ce on the panel in addition to its line of action.

Problem 2.89 The tank in Fig. P2.89 contains benzene in addition to is pressurized to 200 kPa (gage) in the air gap. Determine the vertical hydrostatic as long as ce on circular-arc section AB in addition to its line of action. Fig. P2.89 Consider a cylinder of specific gravity S < 1 floating vertically in water (S = 1), as in Fig. P2.127. Derive a as long as mula as long as the stable values of D/L as a function of S in addition to apply it to the case D/L = 1.2. Problem 2.127 Fig. P.2.127 Problem 2.128 An iceberg can be idealized as a cube of side length L, as in Fig. P2.128. If seawater is denoted by S =1.0, then glacier ice (which as long as ms icebergs) has S=0.88. Determine if this cubic iceberg is stable as long as the position shown in Fig. P2.128. Fig. P2.128

Problem 2.129 The iceberg of Prob. 2.128 may become unstable if its width decreases. Suppose that the height is L in addition to the depth into the paper is L but the width decreases to H < L. Again with S = 0.88 as long as the iceberg, determine the ratio H/L as long as which the iceberg becomes unstable.
