Church organs have a set of pipes with different lengths. With those different pipes organs can produce sounds over a wide range of frequencies. If the lowest frequency produced by an organ is 30.4 Hz, and the highest frequency is 1.48 kHz, then what is the shortest possible wavelength of sound the organ can produce? Assume that the speed of sound is 331 m/s.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
