A section of highway has vertical and horizontal curves with the same design speed. A vertical curve on this highway connects a +1.5% and a +3.5% grade and is 440 ft long. If a horizontal curve on this highway is on a two-lane section with 12-ft lanes and has a central angle of 35 degrees and a super-elevation of 6% what is the length of the horizontal curve?

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.
