A beach ball rides the waves at the beach. The ball moves up and down 3 times every 5.0 seconds. The
speed of the wave is 0.80 m/s. The wavelength of the
wave is m/s.

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.
