Unformatted text preview: A. The pressure at the top of the water is atmospheric pressure plus the pressure produced by the weight of the wood cylinder. This additional pressure p’ is W/A=50/(3.1415*0.15 2 )=707 Pa. The total pressure is p’+p atm =1.013 x 10 5 +707 = 102,007 Pa. B. The pressure at the bottom is p’+p atm + ρ gh= 1.013 x 10 5 +707 + 1000 * 10 * 1 = 112,007 Pa Water Wood...
