1. A metal block 2.5 ft square and 1.5 ft deep remains submerged on a body of liquid which consists of a 12-in layer of water above a 10-in layer of mercury. The block of metal weighs 120 lb/ft3. What is the distance (measured from the bottom) of the block within the mercury (s=13.6)?

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
