Air expands through a turbine operating at steady state. at the inlet, p1 = 150 lbf/in.2, t1 = 1400°r, and at the exit, p2 = 14.8 lbf/in.2, t2 = 900°r. the mass flow rate of air entering the turbine is 17 lb/s, and 65,000 btu/h of energy is rejected by heat transfer. neglecting kinetic and potential energy effects, determine the power developed, in hp.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
