Chapter 8, Problem 160P

It is a well-known fact that Roman aqueduct customers obtained extra water by attaching a diffuser to their pipe exits. The figure shows a simulation with a smooth inlet pipe. with and without a 20 diffuser expanding to a 6-cm-diameter exit. The pipe enhance is sharp-edged, Calculate the flow rare (a) without, and (b) with the diffuser and interpret the results. (c) For the case of a well-rounded entrance. $K_{out}=0.05$ , between the reservoir and pipe inlet for the system with a diffuser, how mitch would the flow rate increase? For water at 2OC. take p = 998 kg 111 and p = 0.001 kg/m.s.
