## Question:

Water falls down a vertical pipe by gravity alone. The flow between vertical locations z_{1} and z_{2} is fully developed, and velocity profiles at these two locations are sketched in Fig. P10–112. Since there is no forced pressure gradient, pressure P is constant everywhere in the flow (P = P_{atm}). Calculate the modified pressure at locations z_{1} and z_{2}. Sketch profiles of modified pressure at locations z_{1} and z_{2}. Discuss.
