Suppose a cold can of coca-cola is sitting on a flat table. the can has a flat circular bottom of area 100 cm2 and the can is coated with a very thin layer (0.01 mm) of condensation (which is why you don't set you coke on an expensive wooden table). how much force must you exert horizontally to move the can with a constant velocity of 1 cm/sec?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
