In an experiment to illustrate the propagation of sound through fluids, identical sound sources emitting at 440 Hz are used to propagate sound waves through mercury and through ethanol.

Medium Sound Speed
Ethanol 1,160 m/s
Mercury 1,450 m/s

Which of the following statements is correct, assuming that the dampening effect in each medium is negligible?

A. In ethanol, the frequency of the wave is greater to compensate for the smaller wavelength
B. In mercury, the frequency of the wave is the same as in ethanol, but the wavelength is greater.
C. In ethanol and mercury, the wavelength of the wave is the same, even if the speed of sound is different.

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
