Question

Fresh water flows horizontally from pipe section 1 of cross-sectional area A1 into pipe section 2 of cross-sectional area A2. The figure gives a plot of the pressure difference p2 - p1versus 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 ?ps = 900 kN/m2.

Fresh water flows horizontally from pipe section 1 of cross-sectional area A1 into pipe section 2 of cross-sectional area A2. The figure gives a plot of the pressure difference p2 - p1versus the inverse area squared A1^-12 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 ?ps = 900 kN/m^2. For the conditions of the figure, what is the value of A2?
