Answer to Question #288561 in Classical Mechanics for joseph

Question

1.A trapezoidal channel with an 18-ft-wide bottom and side slope m = 2 discharges 300 cfs. The natural channel (clean/straight) has a 0.04 ft/ft bottom slope. Compute the normal depth of flow using successive substitution and Figure 6.4. Check your solution using appropriate computer software. 

2.A corrugated metal stormwater drain is discharging 55 cfs. Assuming uniform flow in the 4-ft-diameter pipe, determine the flow depth if the 150 ft long pipe goes through a 3-ft drop in elevation. Check your solution using Figure 6.4b and appropriate computer software.
