A hair dryer is basically a duct in which a few layers of electric resistors are placed. A small fan at the back of the device pulls the air in and forces it through the resistors where it is heated (see Fig. 1). The power consumed by the heating elements (i.e. electric resistors) of the hair dryer is 1258 Watts. Air enters the hair dryer at 95 kPa and 25°C and leaves at 50°C. The cross-sectional area of the hair dryer at the exit is 55 cm². The power consumed by the fan is 2 Watts and the heat loss through the walls of the hair dryer is 5 Watts. By clearly stating your assumptions throughout, 1.Analytically describe the Fluid Mechanics and Thermodynamics working principles of the hairdryer; 2.
