Question

For the data in Table P20.21, use polynomial regression to derive a third-order predictive equation for dissolved oxygen concentration as a function of temperature for the case where chloride concentration is equal to 10 g/L. Use the equation to estimate the dissolved oxygen concentration for T = 8°C.

	Dissolved Oxygen (mg/L) for Temperature (°C) and Concentration of Chloride (g/L)

T, C	c = 0 g/	c = 10 g/L	c = 20 g/L
0	14.6	12.9	11.4
5	12.8	11.3	10.3
10	11.3	10.1	8.96
15	10.1	9.03	8.08
20	9.09	8.17	7.35
25	8.26	7.46	6.73
30	7.56	6.85	6.2
