Asubmerged spherical body of volume 0.5 m^3 and density equal to half the density of water is moored in the deep ocean with a taut vertical cable 1000 m long. neglecting all hydrodynamic forces, but including the upward buoyancy force on the body, find the tension in the cable and the natural period of this inverted pendulum. comment on how the unsteady force in section 2.11 would affect this period. estimate the horizontal excur- sion of the buoy and the angle of the mooring cable in a steady current of 0.5 knots

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
