1.Carbon dioxide flows in a 2-in by 3-in duct at a pressure of 46 psi and a temperature of 80 degrees Fahreneit. If the atmospheric pressure is 13.8 psia and the flow velocity is 10 fps, calculate the weight flow rate.

2.The velocity of a liquid (s=1.26) in a 3-in pipeline is 2.4 fps. Calculate the rate of flow in cfs, gal/min, slugs/sec, and lb/sec.

3.A sound wave is observed to travel through a liquid with a speed of 1500 m/s. The specific gravity of the liquid is 1.5. Determine the bulk modulus of elasticity, Ev, for this fluid.

4.Name the three factors that influence the degree to which martensite is formed throughout the cross section of a steel specimen. For each, tell how the extent of martensite formation may be increased.
