A rectangular plate 1.5m wide and 2.5m deep is placed vertically in water so that the center of plate is 4m below the free surface.
Determine the total pressure and the depth of center of pressure. State also whether the equilibrium is stable or unstable. The above
rectangular plate is taken out of the water which weighs 350.5 N in air and 173.3 N in water of specific gravity 0.99. Find the volume and
specific gravity of the plate. Draw a neat sketch

A conventional, rectangular flocculation basin is 38 ft. wide, 90 ft. long and 16 ft. deep. The flow through the basin is 24 mgd and the water horsepower input by the reel type paddles is 15 hp. The dynamic viscosity of water is 2.73 E -5 lb/sec/ft2 at 50 degrees Fahrenheit. The flocculation basin in above is followed by four sedimentation basins which operate in parallel.   Each basin is 30 ft. wide, 240 ft. long and has an effective settling...
