The water flowrate, Q, in an open rectangular channel can be measured by placing a plate across the channel as shown in Fig. P7.17. This type of a device is called a weir. The height of the water, H, above the weir crest is referred to as the head and can be used to determine the flowrate through the channel. Assume that Q is a function of the head, H, the channel width, b, and the acceleration of gravity, g. Determine a suitable set of dimensionless variables for this problem.
Assume that crude oil from a supertanker has density 750 kg/m'. The tanker runs aground on a sandbar. To reflect the tanker, its oil cargo is pumped out into steel barrels, each of which has a mass of 15.0 kg when empty and holds 0.120 m' of oil Y..
