A cylindrical specimen of some hypothetical alloy is stressed in compression. If its original and final diameters are 30.00 and 30.04mm respectively, and its final length is 130.00 mm, calculate its original length if the deformation is totally elastic. The elastic and shear moduli for this material are 65.5 and 25.4 GPa respectively.

Two airstreams are mixed steadily and adiabatically. The first stream enters at 35°C and 30 percent relative humidity at a rate of 15 m3/min, while the second stream enters at 12°C and 90 percent relative humidity at a rate of 25 m3/min. Assuming that the mixing process occurs at a pressure of 90 kPa, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture. Use data from the tables.

a) The specific humidity is __kg H2O/kg dry air.

b) The relative humidity is __ %.

c) The dry-bulb temperature is __ °C.

d) The volume flow rate of the mixture is __m3/min.

Between 1975 and 1985, the volume of all iron and steel in a given automobile model decreased from 0.165 m3m3 to 0.118 m3m3. In the same time frame, the volume of all aluminum alloys increased from 0.012 m3m3 to 0.023 m3m3. Using the densities of pure FeFe and AlAl, estimate the mass reduction resulting from this trend in materials substitution.

An exercise room has six weight-lifting machines that have no motors and seven treadmills, each equipped with a 2.5-hp (shaft output) motor. The motors operate at an average load factor of 0.7, at which their efficiency is 0.77. During peak evening hours, all 13 pieces of exercising equipment are used continuously, and there are also two people doing light exercises while waiting in line for one piece of the equipment. Assuming the average rate of heat dissipation from people in an exercise room is 740 W, determine the rate of heat gain of the exercise room from people and the equipment at peak load conditions.
