Unformatted text preview: CIVIL 2 131 , Fluid Mechanics Tutorial 11 : Buoyancy and stability of floating bodies Covers week 1 1 lecture material Problem ! A 170 - kg granite rock ( P = 2700 kg/m?" ) is dropped into a lake . A man dives in and tries to lift the rock . Determine how much force the man needs to apply to lift it from the bottom of the lake . Do you think he can do it ? ( ans : rock weighs 107 kj under water ) Problem 2 The gate shown consists of one quarter of a circular cylinder and is used to maintain a water depth of H . That is , when the water depth exceeds H], the gate opens slightly and lets the water flow under it . Find the mass Pivot M of the gate per W into the page . TO 5 ph = 4 + 4 - 1 , 1 - 3 7 Problem 3 To what depth d will this rectangular block ( with density 0. 75 times that of water) float in the two- liquid reservoir ? ( d = 2. 04 [ ) P = 0. 75 P water V SG = 1. 0 7 31. d = ? SG = 1.21 GL Problem 4 A cylindrical block of wood of diameter d and length [ has a specific density of s . Establish criteria for which it floats in the water vertically ? Does it float vertically ford = 0. 3 m and [ = 1. 0 m and $ = 0. 76 ? ( 7 > 2 / 2( 1 - 5 ) s and hence it won't float ) 1/1...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
