Aclosed, rigid tank contains a two‐phase liquid–vapor mixture of refrigerant 22 initially at −20°c with a quality of 50.36%. energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6 bar. determine the final temperature, in °c. if the final state is in the superheated vapor region, at what temperature, in °c, does the tank contain only saturated vapor?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
