Aclarifier is holding 50m^3 of turbid water with a tss of 1000 mg/l. you add 1l of flocculent to the clarifier and that causes 47kg of agglomerated flocs (weight after drying) to form in the clarifier’s basin. a. what was the yield of your process? b. what percentage of the suspended solids were removed by the coagulant?

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

i believe the answer is true.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
