An air-standard dual cycle has a compression ratio of 16. At the beginning of compression, p1 5 14.5 lbf/in.2, V1 5 0.5 ft3, and T1 5 508F. The pressure doubles during the constant volume heat addition process.For a maximum cycle temperature of 30008R, determine
(a) the heat addition to the cycle, in Btu.
(b) the net work of the cycle, in Btu.
(c) the thermal efficiency.
(d) the mean effective pressure, in lbf/in.2
(e) To investigate the effects of varying maximum cycle temperature, plot each of the quantities calculated in parts (a) through (d) for maximum cycle temperatures ranging from 3000 to 40008R.
for some applications it is necessary to harden the surface of a steel above that of its interior. one way this may be
If an elevator starting from rest accelerates at 10 m/s^2 and then decelerates at -1 m/s^2 until it reaches the top floor at 100m, calculate the shortest time it takes for it to reach the top floor (ignore gravitational acceleration, assume g=0). plo..
