A1-m ocean wave has a period of 5 sec in the ocean. find the wavelength, the wave velocity, and the energy and power densities for this wave. contrast the results of this exercise with those of example 14.4. how important is wave height in determining wave energy?

Fluids at rest possess no flow energy. a)- true b)- false

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
