Answer the following question
Problem 4. A receipt of surface water sample is given in Table below: Substance Concentration (mg/L) Total Hardness 1000 mg/L CaCO3 Phenolphthalein acidity 5 mg/L CaCO3 Phenolphthalein Alkalinity 3 mg/L CaCO3 It is known that phenolphthalein alkalinity is only due to CO3²- and phenolphthalein acidity is only due to H₂CO3. Assuming the hardness of sample is because of calcium and magnesium ions, alkalinity-acidity are due to the carbonate species, calculate: a) The pH of sample. b) Temporary and permanent hardness as mg/L CaCO3. c) Total alkalinity and acidity as mg/L CaCO3. Molecular weights (g/mole): Ca = 40, Mg = 24, H = 1, C = 12, 0 = 16

Problem 2: Engineers sometimes use pipes as reactors in treatment plants. Suppose that the plant flow is 3.3ft3/s (about 2.1 million gallons per day, mgd) and a cylindrical pipe is to be used for disinfection.A. Draw a sketch of the system. Indicate the control volume by a dashed line. What kind of hydrodynamicmodel should you use for a pipe? What mixing conditions should you assume?B. Write the integrated mass balance equation for the pollutant in symbols at steady state. (“Integrated” meansthat your mass balance looks like: C = …) Define your symbols.C. For a pipe 3.5 feet in diameter and 50 feet long, what is the hydraulic residence time in minutes?D. For the pipe in Part C, what value of the first-order rate constant (in min–1) is needed to achieve a 99% removal of bacteria?
