Fresh water flows horizontally from pipe section 1 of cross-sectional area Al into pipe section 2 of cross-sectional area A2. Figure gives a plot of the pressure difference p2 ?? p1 versus the inverse area squared A1-2 that would be expected for a volume flow rate of a certain value if the water flow were laminar under all circumstances. The scale on the vertical axis is set by Δps = 300 kN/m2. For the conditions of the figure, what are the values of

(a) A2 and

(b) The volume flow rate?
