Il Consider the capability of a process that puts pressurized grease in an aerosol can. The design specification calls for an average of 50 pounds per square inch (psi) of pressure in each can with an upper tolerance limit of 56psi and a lower tolerance limit of 46psi. A sample is taken from production, and it is found that the cans average 51psi with a standard deviation of 2psi. Find the following unknowns. 1. Capability Index (Cpk) 2. Is the process capable at the 30 level? 3. What is the probability of producing a defect? Hind: use the standard normal table as seen below.

The following dissolved-oxygen values were found after 5days of incubation in 310-mL BOD bottles: 7.7, 7.9 and 7.9 in three blank samples; 6.5, 4.0, and 0.5mg/L in bottles containing 2,5, and 10 mL of sample, respectively. The 0-day dissolved-oxygen of the sample was 0.0 mg/L. What is the 5-day BOD of the sample?
A BOD test is run using 100mL of treated wastewater. The initial DO of the mixture after diluting the waste sample with distilled water is 9.0mg/L. After 5-day incubation, the DO measured was 4.0mg/L. After a long period of time, the DO is 2.0mg/L and no longer seems to be decreasing. Assume that nitrification has been inhibited. Determine the following: a)BOD5 & BODu of the waste sample b) BOD5 of the mixture and c) k THANK YOU
Suppose the estimated BOD of an influent sample is expected to be 150 mg/L and the dissolved oxygen concentration of the oxygen saturated dilution water used in the BOD test is 8.5 mg/L. If you are using a 300 mL BOD bottle, estimate the maximum and minimum amount of sample you would add to the BOD bottle to ensure satisfactory test results. NOTE: Acceptable BOD test should comply with the two essential criteria: DO final ≥ 2 mg/L and DO initial – DO final ≥ 2 mg/L. Assume that the dilution water is the only source of oxygen.
A 50 ml sample of industrial wastewater is taken into a silica crucible. The empty weight of the crucible is 54.352 g. The crucible with the sample is dried in a hot air oven at 104°C till a constant weight of 55.129 g. Thereafter, the crucible with the dried sample is fired at 600°C for 1 h in a muffle furnace, and the weight of the crucible along with residue is determined as 54.783 g. The concentration of total volatile solids is
Jar testing was performed using alum on a raw drinking-water source that contained an initial turbidity of 20 NTU and an alkalinity of 35 mg/L as CaCO3. The optimum coagulant (alum: Al2(SO4)3•14H20) dosage was determined as 18 mg/L with a final turbidity of 0.25 NTU. Determine the quantity of alkalinity consumed as mg CaCO3 (1 significant figure)
A standard BOD test is run using seeded dilution water. The blank bottle containing the seeded dilution water has an initial DO of 9.2 mg/L and a final DO of 8.2 mg/L. The waste sample is mixed with seeded dilution water at a 1:25 ratio. It has an initial DO of 9.0 mg/L and a final DO of 2.0 mg/L. Calculate the BOD5.
