Three vertical columns, A with constant circular cross section, B with tapered circular cross section and the narrow end below, and C with tapered circular cross section and the broader end below, are sitting half-submerged in water on an impermeable floor. Which of the following statement(s) is (are) correct if the volume of water displaced by each column is identical? (i) The up thrust for each column due to hydrostatic pressure is identical according to Archimedes principle. The up thrust due to hydrostatic pressure is highest for column B. The up thrust due to hydrostatic pressure for column C is negative. (ii) (iii) (A) (B) (ii) (iii) The Bernoulli equation requires the flow to be inviscid and along a streamline. However Bernoulli equation can be used to measure the velocity at a point in viscous boundary layer or pipe flow. The reasons for such applicability are: (i) The stagnation pressure along a streamline is constant. The static pressure along a streamline over a short distance is constant. The dissipation of useful energy along a streamline over a short distance is negligible. (i) and (ii) (i) and (iii) (ii) and (iii) (i) only (A) (B) (C) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above
