Question: Table P15.5 lists values for dissolved oxygen concentration in water as a function of temperature and chloride concentration. Table P15.5 (a) Use quadratic and cubic

Table P15.5 lists values for dissolved oxygen concentration in water as a function of temperature and chloride concentration.

Table P15.5

T, C 0 5 10 15 20 25 30 Dissolved Oxygen (mg/L)

(a) Use quadratic and cubic interpolation to determine the oxygen concentration for T = 12°C and c = 10 g/L.

(b) Use linear interpolation to determine the oxygen concentration for T = 12°C and c = 15 g/L.

T, C 0 5 10 15 20 25 30 Dissolved Oxygen (mg/L) for Temperature (C) and Concentration of Chloride (g/L) c = 0 g/L 14.6 12.8 11.3 10.1 9.09 8.26 7.56 c = 10 g/L 12.9 11.3 10.1 9.03 8.17 7.46 6.85 c = 20 g/L 11.4 10.3 8.96 8.08 7.35 6.73 6.20
