Aproposal is to build a 1000-mw electric power plant with steam as the working fluid. the condensers are to be cooled with river water. the maximum steam temperature is 550 celsius, and the pressure in the condensers will be 10 kpa. the river is 60 m wide and 8 m deep, and flows at a velocity of 10 m/min. estimate the temperature rise of the river downstream from the power plant.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

On a average work day more than work place firs are reorted

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