Your intuition should by now indicate that the reverse process of the air that was originally confined to one side of a chamber and allowed to expand to fill the entire chamber is impossible. To prove it to be impossible, we can conduct a second law analysis to assess the entropy produced. If the value for the entropy produced is negative, then in fact it is proven to be impossible. Report the entropy produced in units of kJ/K and report your answer using 3 significant digits. Consider the following:
m = 2.1777kg
P1 = 250kPa
Vi = 1m ^3
T2 = T1 = 400K
P2 = 500kPa
V2 = 0.5m^3

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.
