1.Data obtained from aerial photography showed six vehicles on a 600 ft long section of road. Traffic data collected at the same time indicated an average time headway of 3.6 sec. Determine the (a) density on the highway (b) flow on the road (c) space mean speed.
2.Design a broad crested weir for a laboratory flume with a width of 1.25 ft. The discharge range is 0.1 to 1.0 cfs. The maximum approach flow depth is 18 inches. Determine the height of the weir P and the weir length l in the flow direction. Assume cv =1.
