Aflat piece of glass covers the top of a vertical cylinder that is completely filled with water. if a ray of light traveling in the glass is incident on the interface with the water at an angle of θa = 36.0 ∘, the ray refracted into the water makes an angle of 49.5 ∘ with the normal to the interface.
what is the smallest value of the incident angle θa for which none of the ray refracts into the water?

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
