A0.2-m-long and 25-mm-thick vertical plate (k=15 w/m∙k) separates the hot water from the cold water. the plate surface exposed to the hot water has a temperature of 100°c, and the temperature of the cold water is 7°c. determine the temperature of the plate surface exposed to the cold water (ts, c). hint: the ts, c has to be found iteratively. start the iteration process with an initial guess of 53.5°c for the ts, c.

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

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)
