The air standard brayton cycle is a type of idealized gas power cycle depicted in the schematic below. some of the power produced by the turbine is used by the compressor; the rest is the net work for the cycle. kinetic and potential effects are negligible. stray heat transfer from the turbine and compressor can be neglected. data are provided for the system operating at steady state. the air can be treated as an ideal gas. you may choose to model the air with constant specific heats using k=1.4 what is the thermal efficiency of the cycle? (recall eta=wcycle/qin). express the value as a decimal, not as a percent (i. e., 0.32 instead of 32%).

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
