Question

75m high stack emits a plume at 20 degrees 6. a75 m high stack emits a plume at 20 °c. the ground temperature is 16 °c, and the prevailing lapse rate is -10.1 °c/km up to an altitude of 250 m. above 250 m, the prevailing lapse rate is 19.8°c/km. assume the gas exits the stack at near-zero velocity, and assume a negligible wind speed.

a.

b.

c.

d.

e. what type of atmospheric stability conditions exist? how high will the plume rise? what type of plume will be formed? what is the maximum mixing depth? how is the dry adiabatic lapse rate affected by a water-saturated atmosphere?
