If you shined a light through air into water, glass, or a diamond, at an angle of incidence of 0,-70.70, would the angle of Use Snell's Law and the table below to calculate the angle of refraction 0, be the same in each medium?U refraction 0, for each medium. Note that the index of refraction of air (n) is 1.00, rounded to the nearest 0.01. Ro Sin2 Medium Water Glass Diamond n2 1.33 1.52 .42 0, show calculator readin SIN

A cross-flow heat exchanger is used to heat mixed air from 20 ºC to 45ºC. Water at 75ºC enters the tube and leaves at 45ºC. If the overall heat transfer coefficient is 50 W/m^2?ºC and there is to be 30,000 W of heat exchanged, determine the necessary heat exchanger surface area and the mass flow of water.

What will be an ideal response?
