Simple equation of state when solving problems always show your work and never forget units. pe 1027%, +[a(t-10,c)+b(s-35psu)-kp] answers without units /m are meaningless ã--0.15kg " %, s per 'c b-078k% per psu k-4.5x10s kg/per decibar 1. use the equation of state above to calculate the following: calculate density and sigma for t-25c, s-32 psu at the sea surface. b. calculate density and sigma for t a. 2ec, s 36 psu at a depth of 4000m (4000 db) calculate density and sigma for t-10°c, s-27 psu at the sea surface c. 2. use the std diagram below to answer the following questions. a. what does the letter sigma designate in this diagram? b. plot a water mass a which has a sigma value of 27.5 and temperature of o degrees c. c. next plot a water mass b which has a sigma of 27.5 and a salinity of 35%. d. do both of these water masses have the same density? e. draw a straight line connecting point a to point b. this is the mixing line of these two water masses and its midpoint is the 50: 50 mixture of these two water masses. f. what is the temperature of the 50: 50 mixture of water masses a and b? g. what is the salinity of the 50: 50 mixture of water masses a and b? h. what is the density of the 50: 50 mixture of water masses a and b? i. is the 50: 50 mixture more or less dense than either a or b? j. is there any point on the mixing line where the density of the mixture is less dense than either water mass a or b? k. what is this phenomenon called?
