Chapter 5 – Problem 5.10

5.10 Suppose that the surge tank described in the previous example is a bladder surge tank with a 400 mm perforated grid (see Figure 5.32) attached at the bottom of the tank. Compute the total resistance of the connecting pipeline, including the perforated grid, if the effective area of the perforated grid is 30% of the plate area and a discharge coefficient of 0.55 is a reasonable estimate for use when computing the grid resistance.
