WebNov 9, 2024 · 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. ... Where V' is volumetric flow rate = Av. Thus; m' = ρAv. Where; ρ is density . A is area. v is velocity. Therefore from m'1 = m'2, we can say that ... WebNov 12, 2024 · Answer: a) volume flow rate of air at the inlet is 0.0471 m³/s b) the velocity of the air at the exit is 8.517 m/s Explanation: Given that; The electrical power Input W_elec = -1400 W = -1.4 kW Inlet temperature of air T_in = 22°C Inlet pressure of air p_in = 100 kPa Exit temperature T_out = 47°C Exit area of the dyer is A_out = 60 cm²= 0.006 m² WebDischarge velocity = volume flow rate of air area of duct = 4.67 m / s \frac{\text{volume flow rate of air}}{\text{area of duct}}=4.67 \ \mathrm{ m/s} area of duct volume flow rate of air = 4.67 m/s. b) Now we need to let go off the assumptions that … covestro llc pittsburgh pa
