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.
Conditions in the sewage pipe are Qs= 0.5 m^3/s, and Cs= 100mg/L. The pollutant is destroyed in the lake with a first-order rate constant of 0.2/d. The flow rate out of the lake is 5.0 m^3/s.

The fountain shown is designed to provide a stream of water that rises h=10ft to h=20 ft above the nozzle exit in a periodic fashion. To do this the water from the pool enters a pimp
Estimate the value of the coefficient of at-rest earth pressure forthe deposit. If, when the water table was at the ground surface, the deposit was normallyconsolidated,would it still be normally consolidated with the water tablelowered? A reason mus..
A balloon is to be used to carry meteorological instruments to an elevation of 15,000 ft where the air pressure is 8.1 psia. The balloon is to be filled with helium, and the material from which it is to be fabricated weighs 0.01 lbf/ft^2.
what is the engineering ethics course where to write about any engineering ethical case and discuss the ethical issue?
