Estimating salinity Salinity of the ocean refers to theamount of dissolved material found in a sample of seawater.Salinity S can be estimated from the amount C of chlorinein seawater using S = 0.03 + 1.805C, where S and C aremeasured by weight in parts per thousand. Approximate Cif S is 0.35.

When purifying drinking water you can use a so-called membrane filtration. In an experiment one wishes to examine the relationship between the pressure drop across a membrane and the flux (flow per area) through the membrane. We observe the following 10 related values of pressure (x) and flux (y): 1 2 3 4 5 7 8. 9 10 Pressure (x) 1.02 2.08 2.89 4.01 5.32 5.83 7.26 7.96 | 9.11 9.99 Flux (y) 1.15 0.85 1.56 1.72 4.32 5.07 5.00 5.31 6.17 7.04 (a) Fit the least square regression equation to predict the flux (flow per area) through the pressure drop across a membrane.

A lower limit estimate for the amount of material leaked after 4 hours is gal. (Simplify your answer.) An upper limit estimate for the amount of material leaked after 8 hours is (Simplify your answer.) gal. A lower limit estimate for the amount of material leaked after 8 hours is gal. (Simplify your answer.) If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 20,000 gallons of material, an estimate for the least amount of time for the tank to empty is hr. (Round to the nearest tenth as needed.) If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 20,000 gallons of material, an estimate for the most amount…
