Question

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 entrance is sharp-edged. Calculate the flow rate (a) without, and (b) with the diffuser and interpret the results. (c) For the case of a well-rounded entrance, Kent = 0.05, between the reservoir and pipe inlet for the system with a diffuser, how much would the flow rate increase? For water at 20°C, take ρ = 998 kg/m3 and μ = 0.001 kg/m·s.
