Apilot can withstand an acceleration of up to 9g, which is about 88 m/s2, before blacking out. (a) what is the acceleration experienced by a pilot flying in a circle of constant radius at a constant speed of 515 m/s if the radius of the circle is 2710 m? (b) does the pilot make the turn without blacking out?

Ahair dryer is basically a duct 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. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
