5. An object of density 0.5678 kg/m° is floating in a fluid of density 1.543 kg/m. What
percent of the object is underneath the fluid?
6. Steam (ideal fluid) is rushing steadily from a boiler through a slowly varying conical
pipe, the diameters of the ends being 2a and 5a/2, respectively. Assume that the body
forces are absent. If U and V are the uniform velocities at the ends, prove that
U 25
- еxp
