An internal combustion engine operating on the Otto cycle has a pressure and temperature of 13.0 psia and 70.0°F at the beginning of the compression stroke (state 3 in Figure 13.48) and a pressure at the end of the compression stroke of 200. psia. For the cold ASC with k = 1.40, determine
a. The compression ratio, CR.
b. The temperature at the end of the compression stroke.
c. The thermal efficiency of the cycle.
Two sinusoidal waves, identical except for phase, travel in the same direction along a string producing a net wave y'(x, t) = (2.5 mm) sin(17x - 4.0t + 0.840 rad), with x in meters and t in seconds. (Assume that the phase constant for one of the i..
