Question

A sea water float consists of a cylinder and cone combined as shown here below. The density of sea water is 1026 kg/m3 and g = 9.81 m/s2

Calculate the total upthrust in kN which is exerted on the float when it is totally immersed in the ocean.

Draw a labelled diagram showing the float, the water level and all forces acting on the float. Dimensions are: D = 0.6m, H = 1.0m, h = 0.8m

Answer 1

Pw= 1026 kg/m3 g = 9.81 m/s? D = 0.67 H = 1 m h 0.8m D H Volume of fleet & = 1 1 10 24 N = 14 + 1/ 8 x 17 1026 4 12 (4+1/3) px 0,6*X (1+0) V: t V = 0.35814 m2 fone float floct - Buoyancy Upthrust exerted on Ft Pw &g = 1026 X 0.35814 x 9.81 > Ft = 3604. 7. IN 02 Ft = 3.605 KNI 05kn
