Chapter 09a Process Capability and Statistical Process Control Review and Discussion Questions 1. The capability index allows for some drifting of the process mean. Discuss what this means in terms of product quality output. When Cpk is larger then 1.33 or 1.5‚ this means that the mean of the process can drift (up to a limit) while still producing within specifications. This is what is implied by the phrase “a capable process." 2. Discuss the purposes and differences between the P-charts

| Next‚ we used stoichiometry to calculate the necessary mass of reactants to produce about 2 grams of silver: [pic] [pic] The limiting reactant is the reactant in a chemical reaction that limits the amount of the product that can be formed. The reaction will not continue after all of the limiting reactant is consumed. The limiting reactant in our reaction is Cu because we want the entire amount of the element to bond with the AgNO3. The excess reactant is the reactant in a chemical

Ecology is the study of the relationship of between organisms and their environment‚ including both the living and nonliving compounds. Some of the ecological concepts include succession‚ energy flow between trophic levels‚ limiting factors‚ and carrying capacity. First‚ succession is a change in species structure of an ecological community over time. Over time species in the community become more and more abundant and may not be present at all one day. Also‚ sometimes new species might invade the

of oxygen that the body can consume‚ transfer‚ or employ during a given exercise is called VO2max. This indicates the physical well-being of an individual. However‚ a multitude of physiological functions limit a person’s endurance for exercise by limiting maximum oxygen consumption by the body (Katch et al.‚ 2011). VO2max is used to determine the fitness levels‚ not only in athletes‚ but also in patients with heart failure‚ and is therefore both a prognostic and diagnostic tool. It is measured as

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method

the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation was salicylic acid. After the limiting reactant was determined‚ the theoretical yield of aspirin was calculated at approximately 1.97g. The actual yield was only around 0.67g‚ producing a percent yield of 34.3%. These results show that the methods used
