The flywheel turns clockwise with a constant speed of 670 rev/min, and the connecting rod ab slides through the pivoted collar at c. for the position θ = 57°, determine the angular velocity ωab (positive if counterclockwise, negative if clockwise) of ab by using the relative-velocity relations. (suggestion: choose a point d on ab coincident with c as a reference point whose direction of velocity is known.)

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.
