Question

Exercise 10.
The y = 0 plane separates air in the upper half-space (y > 0) from a good conductor (y ≤ 0) while a
surface charge density, p = C₁ sin ßx, and a surface current density, K = C₂ cos ßx, are present at
the interface. (C₁,C₂ and ß are constants).
Find expressions for E and H in the air at the interface.
Ans.
E = 9¹sin ßx; H = 2C₂ cos Bx

B A hair dryer is basically a duct of constant diameter in which a few layers of electric resistors are placed. A small fan pulls the air in and forces it through the resistors where it is heated. If the density of air is 1.15 kg/m3 at the inlet and 1.05 kg/m3 at the exit, determine the percent increase in the velocity of air as it flows through the hair dryer 1.05 kg/m³ The increase in velocity is Pin kg/m³ Check my work %6
