3. A 0.9 ft diameter steel stud is mounted upright to the seabed at a water depth of 32 ft. If the pipe is hit by 4.5 ft high waves, exhibiting a wavelength of 26 ft, calculate the: (i) Max. fluid velocity at the free surface (z=0), (ii) Flow regime (e.g., critical) and type of flow, and [2.5] [2.5] (iii) Keulegan-Carpender number & identify the pertinent flow regime and type. [13] Seawater mass density is 2.0 slugs/ft. Kinematic viscosity of seawater is 1.110-5ft/s. Hint: the max. velocity is obtained at the origin, at t=0. [6%] 3.
