1.A rectangular channel of width b is to carry water at flowrates from 30 ? Q ? 600 cfs. The water depth upstream of the hydraulic jump that occurs (if one does occur) is to remain 1.5 ft for all cases. Plot the power dissipated in the jump as a function of flowrate for channels of width

b = 10, 20, 30, and 40 ft.

2.The aerodynamic drag on a car is to be predicted at a speed of 60.0 mi/h at an air temperature of 25?C. Automotive engineers build a one-fourth scale model of the car to test in a wind tunnel. Determine the required air speed in the wind tunnel. If the aerodynamic drag on the model is measured as 36.5 lbf, estimate the drag at full-scale.
