Adischarge of warm water from a coastal power plant is located at 80 m depth. the sea is assumed to be well mixed and quiescent. the warm water discharges upwards at a velocity of 2.0 m/s and the exit diameter of the discharge outlet is 1 m. the velocity is initially uniform across the outlet. the initial density step is 1 kg/m3.

a. estimate the maximum concentration of a tracer at a depth of 20 m if the initial concentration is 1 kg/m3 .
b. a monitoring station is set up at 20 m depth and 5 m off the vertical axis of the discharge. what is the expected mean concentration of tracer at this location?
c. a new discharge pipe is being installed. should the diameter be increased or decreased to increase the dilution if the volume flowrate is to stay the same?

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.

hope this

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
