Efrigerant-134a is expanded isentropically from 600 kpa and 70°c at the inlet of a steady-flow turbine to 100 kpa at the outlet. the outlet area is 1 m2, and the inlet area is 0.5 m2. calculate the inlet and outlet velocities when the mass flow rate is 0.75 kg/s.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
