A point source Gaussian plume model for a power plant uses 50 m as the effective stack height. You are concerned about pollutant levels at night, and the night is typically fully overcast with a wind speed of 5 m/s. Your concern in with ground-level pollution at two house locations, A and B, which are 1.2 and 1.4 km directly downwind from the stack.  (a) At what distance will the maximum concentration of pollution occur under these conditions? Which location (A or B) would have the higher level of pollution? (b) Suppose during the day the sky clears up, and the atmosphere becomes moderately unstable, and the wind speed stays around 5 m/s. Will the location downwind at which the maximum concentration occurs move? If so, will it move closer to the stack or further away from the stack? (H remains 50 m). (c) Under the new conditions in part b, which house would experience the most pollution?

A pumping station at sea level is to supply 18000 m3/hour to the located at an altitude of 1694 m above sea level. The first junction of the distribution network is at 20 km from the banks of the river (where the pumping station is installed). Due to obstacles the piping will be first directed 600 North-East for 5 km, then 450 North-West for 7 km the straight easterly on the remaining distance. Taking into account the possible losses, design the piping and related equipment (valves, flanges, elbows, pumps etc) necessary in a daily water distribution.

Convert 100 micrograms per cubic meter of ozone to ppm. T=300K, p at z=10km is 21880kgm^-1s^-2, dT/dz = -0.789gamma, gamma = -0.00976 degrees C per meter

Discharge required??

a) What regions show the largest oceanic latent heat loss? b) What regions show the saltiest surface waters? c) What is the main factor affecting the two radiation heat flux terms? Name the two fluxes. d) What is the main factor affecting the two turbulent heat flux terms? Name the two fluxes.

Calculate the pressure drop for the cyclone of Problem 4,2, assuming K =14,

A ground level contamination source emits 0.45 g/s of a toxic gas into a 2.5 m/s wind. Assuming no initial rise of the gas at the point of release, what is the maximum ground-level concentration (in µg/m3) 500 m downwind from the source if the plume's standard deviations are oy = 76 m and oz = 38 m?

A river has dry-weather discharge of 100 cfs and a temperatureof 25oC. Compute the max. discharge of cooling water at 65oC that can bedischarged from a power plant into the stream. Assume the legal limit ontemperature increase in the stream is 2oC.

A point source Gaussian plume model for a power plant uses 50 m as the effective stack height (see below). The night is overcast. The overcast weather, as defined by the World Meteorological Organization, is the meteorological condition of clouds obscuring at least 95% of the sky. Your concern is with ground-level pollution at two locations, A and B, which are 1.2 and 1.4 km directly downwind from 2. the stack. Night, overcast H= 50 m 1.2 km 1.4 km (a) At what distance will the maximum concentration of pollution occur? Which location (A or B) would have the higher level of pollution? (b) Suppose the sky clears up, and the windspeed stays less than 5/s. Will the location downwind at which the maximum concentration occurs move? If so, will it move closer to the stack or further away from the stack? (H remains 50 m) (c) Under the new conditions in part b, which house would experience the most pollution?
