List 6 different mechanisms in the RubeGoldberg picture and predict the purpose of each. Does the mechanism change speed, force, torque, direction, or type of movement.

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.
