Determine the equivalent diameters (d.) of the following each flow geometries. Calculate the frictional pressure loss gradient for these flow geometries when the flow rate is 500 gal/min, flow behavior index of (n) is 0.75 and a flow consistency index (K) is 90 eq cp. Geometry-1 Geometry-2 Geometry-3 Di=4-in Li= 4-in. Wi=3-in D2=8-in. W=8-in. L2=8-in NOTE: Subscription 1 denotes the size of inner shape and Subscription 2 denotes the size of outer shape. The figures are circles, equilateral triangles and squares.
