True/False?Justify your answer

If wind speed in a rural setting is 4m/s at 10 m from ground levelon a brightand clearsunny day, it will exceed12 m/s at thelocation of emission of pollutants from a 100-m tall stack

Answer #1

Answer = False

Because the wind speed follows the following relation:

where, v2 = 12m/s

v1= 4 m/s

Z2 = 100m

Z1 = 10m

the alpha = wind shear exponent (which has value between 0.1 - 0.2)

Thus, if given wind speed increases to 12 m/s the alpha must be around 0.47, which is not possible in a clear sunny day.

Therefore, it's a FALSE statement.

Upvote, if the answer was helpful. Thanks and have a nice & safe day.

On an afternoon with moderate incoming solar radiation and an average wind speed of 2.5 m/s at a height of 10 m above the ground surface, a power plant emits sulfur dioxide at a rate of 1 kg/s. The effective height of stack is 130 m. The wind speed at the effective stack height is 2.8 m/s. Calculate the concentration (in μg/m3) of sulfur dioxide at ground elevation, directly 3 km downwind from the stack (show hand calculation for this...

For each of the following, answer True or False. Justify your answer! Acceleration can only change the speed of an object. If an object is moving in the x-direction but not the y-direction at one moment in time, then it will never be able to move in the y-direction. A projectile accelerates only in the vertical direction. Conservation of momentum can be applied along both axes in a collision.
