1.A 300 acre parking lot has a runoff coefficient of 0.8 and a time of
concentration of 40 minutes. Using the rational method (Q=CIA), what is peak Q if a
4″/hr rain falls for 10 minutes?
2.Coal has about 2% sulphur. how many kilograms of sulphur would be emitted from
coal fired power plants in the united states in 1 year?(u.s electricity production
is about 0.28*10^12 watts and coal has an energy content of about 30*10^6 j/kg.
note that 1j=1w-sec)
3.Explain the slipping of atoms and the effect on material deformation.
4.Brine flood in a 1.9-in-long and 1.5-in-diameter core plug from the North Sea
resulted in a stabilized pressure drop of 46.05 psi. The flood was carried out at
0.05 mL/min with brine viscosity of 0.443 cP. Determine the absolute permeability
of this plug in millidarcies.
