16.21 A wall 0.6 m high by 3 m wide is maintained at 79°C in an atmosphere at 15°C. Neglecting end effects and radiation, calculate the rate of heat loss by natural convection. For natural convection from a vertical flat surface take, at any distance, $x$: $Nu_x = 0.509(Pr)^{1/2}(Pr + 0.952)^{-1/4}(Gr_x)^{1/4}$ where all properties are at the mean film temperature, and $\beta = 1/T$, where $T$ is the absolute temperature of the bulk of the air.

Answer (T) for true or (F) for false: 1. Uniform plane waves always have field components pointing in the direction of propagation() 2. All waves in space behave like plane waves when observed far enough away from the source() 3. Waveguides cannot support TEM wave. () 4. The region inside the Smith chart describes all possible reflection coefficients for passive circuits. () 5. Electromagnetic waves travel faster in dielectric with $\epsilon_r > 1$ than they do in air. () 6. Waves on lossless transmission lines are TEM waves, much like plane waves.() 7. The characteristic impedance of a lossy line is a real value. () 8. A standing-wave occurs whenever there are two counter-propagating waves of the same frequency() 9. The characteristic impedance of a distortionless line is of complex value. () 10. The standing wave ratio on a matched transmission line is unity. ()
