An eight-lane freeway (four lanes in each direction) is on rolling terrain and has 11-ft lanes with a 4-ft right-side shoulder. The total ramp density is 1.5 ramps per mile. The directional peak-hour traffic volume is 5400 vehicles with 6% large trucks and 5% buses (no recreational vehicles). The traffic stream consists of regular users and the peak-hour factor is 0.95. It has been decided that large trucks will be banned from the freeway during the peak hour. What will the freeway’s density and level of service be before and after the ban? (Assume that the trucks are removed and all other traffic attributes are unchanged.)

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
