( = 1,260 Kg/m 3 and = 1.50 N s/m 2 for glycerin at 20 C) 4. The water flowrate, , in an open rectangular channel can be measured by placing a plate across the channel as shown in Fig. 4. This type of a device is called a weir . The height of the water, , above the weir crest is referred to as the head and can be used to determine the flo-wrate through the channel. Assume that is a function of the head, , the channel width, , and the acceleration of gravity, . Determine a suitable set of dimensionless variables for this problem. Figure 3 Figure 4 2...
