The setting sun is actually visible after it has dropped below the horizon due to the bending of light waves entering the atmosphere at a non-perpendicular angle to the surface, a process known as

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.
