![]() ![]() ![]() It's heavy, has a steel deck, and has three. The Cat mower is configured like gas engine machines. $630 at Amazon $650 at Tractor Supply Co. The specific gravity of wooden block is 0.7.CAT CAT DG671 steel deck self-propelled battery mower. Find the volume of water displaced and the position of center of buoyancy. ![]() A wooden block of width 2m, depth 1.5m and length 4m floats horizontally in water. Solution: Buoyant force per m = Weight of water displaced per m = 12039N/m Buoyant force for 3m (F B3) = 12039x3 = 36117N Weight for 3 m of pipe (W 3) = 22369N Upward force on each anchorage = F B3 – W 3 = 36117-22369 = 13748N 3. Calculate the buoyancy force per meter run and upward force on each anchorage. It is laid across the bed of a river, completely immersed in water and is anchored at intervals of 3m along its length. A steel pipeline carrying gas has an internal diameter of 120cm and an external diameter of 125cm. ![]() Solution: a) Weight of pontoon = Weight of water displaced W = 9810圆x10x2 = 1177200 N = 1177.2 KN b) Draught in sea water (D) = ? Weight of pontoon = Weight of sea water displaced 1177200 = 1177200 = D = 1.95m c) D max = 2.3m Load that can be supported in fresh water (P) = ? Total upthrust (F B) = Weight of water displaced = 9810圆x10x2.3 = 1353780N = 1353.78KN P = F B – W = 1353.78-1177.2= 176.58 KN 2. Calculate (a) weight of pontoon, (b) its draught in seawater of density 1025 kg/m 3 and (c) the load that can be supported by the pontoon in fresh water if the maximum draught permissible is 2.3m. A rectangular pontoon has a width of 6m, length of 10m and a draught of 2m in fresh water. ![]()
