Is air pressure higher above an airfoil? The shape of an airfoil causes air to flow faster on top than on bottom. The fast flowing air decreases the surrounding air pressure. Because the air pressure is greater below the airfoil than above, a resulting lift force is created. Why does the air flow faster over […]
How do you calculate ZL?
How do you calculate ZL? Line impedance is the ratio of complex line voltage to complex line current. You can calculate it with the following equation: Z(z) = V(z)/I(z). How do you find the input impedance of a transmission line? The input impedance of a terminated lossless transmission line is periodic in the length of […]
