Unformatted text preview: at its boundaries. In response to this new boundary condition, internal viscous stresses in the fluid begin to straighten out the velocity profile as the fluid moves along, and eventually, at some station (2), the velocity becomes uniform at the average value V . (a) Does Bernoulli's equation apply in this flow between (1) and (2)? Explain. ANSWER (b) Neglecting gravitational and surface tension effects, find the radius contraction ratio R 2 /R 1 that occurs in the liquid stream after it emerges from the pipe, and the velocity ratio V u m .
