Fresh water flows horizontally from pipe section 1 of cross-sectional area A, into pipe section 2 of cross-sectional area `A_(2)` Figure gives a plot of the pressure difference `p_(2) - p_(1)` versus the inverse area squared `A_(1)^(-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 `Deltap_(s) = 600 kN//m^(2)`. For the conditions of the figure, what are the values of (a) `A_(2)` and (b) the volume flow rate?

Explanation

(a) 0.25 `m^(2), (b) 8.7 m^(3)//s`
