A hair dryer is basically a duct of constant diameter in which a few layers of electric resisiotrs are placed. A small fan pulls the air in and forces it through the resistors where it is heated. If density of air is 1.2 kg/m^3 at the inlet and 1.05 kg/m^3 at the exit, determine the percentage increase in the velocity of air as it flows through the hair dryer.
