Given the following data, determine the water flux rate coefficient (kw) in units of s/ft and the solute mass transfer coefficient (k; ) in units of ft/s conversion factor: 1 psi-6.8948 kpa feed flow rate- 1.o mgd feed tds concentration-2,500 mg/l permeate tds concentration- 20 mg/l net operating pressure-406 psi membrane area-18,300ft2 recovery (r)-90%

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

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.
