Air enters the compressor of an ideal cold air-standard brayton cycle at 100 kpa, 300 k, with a mass flow rate of 6 kg/s. the compressor pressure ratio is 10, and the turbine inlet temperature is 1400 k. for k = 1.4 and cp = 1.005 kj/kg, calculate: (a) the percent thermal efficiency of the cycle. (b) the back work ratio. (c) the net power developed, in kw.

not really sure but thinking 1.54 mm/us

28. evolution

explanation:

the independent variable, or the one that is intentionally manipulated is the speed.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
