A horizontal curve on a single-lane freeway ramp is 400ft long, and the design speed of the ramp is 45mph. If the superelevation is 10% and the station of the PC is 17 35, what is the station of the PI and how much distance must be cleared from the center of the lane to provide adequate stopping sight distance

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3
