R-134a enters a tubular heat exchanger at 100 f with a quality of 75%. heat is transferred out of the system in an aergonic process, until the fluid leaves as saturated liquid at 0f. determine the heat transfer per lbm of r-134a flowing through the heat exchanger. neglect any changes in kinetic and potential energies. assume steady-state operation.

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?
