Race-track turns are often "banked" (tilted inward) so that cars can take them at high speed without skidding. consider a circular track 2km in length banked at an angle of 20o , and just for fun suppose the track is covered in ice (after a bad storm, lets say). with what speed does a car have to drive in order to make it around the track?

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.
