A25-ft wide river running 22-feet deep is impinging on the upstream side of a bridge but not on the downstream side. if the bottom cord of the bridge is normally 15-feet above the riverbed, determine the flowrate of the river. (assume an energy coefficient (α3) of 0.86). (ans: q = 9,012 cfs)

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
