)(10 points) an equal-tangent sage curve has its pvi at station 10+00 and elevation at 138 ft. directly above the pvi, the bottom of an overpass structure is at elevation 162 ft. the pvc is at station 4+00. if the initial grade is -4%, what is the highest possible value of the final grade given that a 70 mph design speed is to be provided in daytime condition? what is the highest possible final grade i nighttime conditions? (ignore the cross-sectional width of the overpass)

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
