2) (40%) True or false? a) For horizontal flow of a liquid in a rectangular duct between parallel plates, the pressure varies linearly both in the direction of flow and in the direction normal to the plates. b) For flows occurring between r= 0 and r= a in cylindrical coordinates, the term In r may appear in the final expression for one of the velocity components. c) For flows in ducts and pipes, the volumetric flow rate can be obtained by differentiating the velocity profile. d) If, in three dimensions, the pressure obeys the equation Op/ dy = -pg, and both Op/ Ox and op/ öz are nonzero, then integration of this equation gives the pressure as p = -ogy+c, where c is a constant. =
