The data listed below are claimed for power cycles operating between hot and cold reservoirs at 1000 k and 400 k, respectively. for each case determine whether such a cycle is in keeping with the first and second laws of thermodynamics. (a) qh 5 300 kj, wcycle 5 160 kj, qc 5 140 kj. (b) qh 5 300 kj, wcycle 5 180 kj, qc 5 120 kj. (c) qh 5 300 kj, wcycle 5 170 kj, qc 5 140 kj. (d) qh 5 300 kj, wcycle 5 200 kj, qc 5 100 kj.

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.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
