1.Carbon dioxide at 30 ?C and 320 kPa absolute pressure expands isothermally to an absolute pressure of 170 kPa. Determine the final density of the gas.

2.A shaft 10.00 cm in diameter and 85 cm long is pulled steadily at V ??0.4 m/s through a sleeve 10.03 cm in diameter. The clearance is filled with oil, with a kinematic viscosity of 0.003 m2 /s and SG ??0.88. Estimate the force required to pull the shaft.

3.A blimp is approximated by a by a sphere of 25 m in diameter. Estimate the weight of 15°C gas within the blimp for (a) helium at 1.1 atm; and (b) air at 1.0 atm. What might the difference between these two values represent?

4.Determine the components Fa and Fb of the 4.2 kN force along the oblique axes a and b. Determine the projections Pa and Pb of F onto the a- and b-axes.
