  1. An oxygen sensor is used to measure the ratio of the oxygen concentration level in the air of that in the combustion stream in an internal combustion engine. Assume the concentration of oxygen in the air is 20.8% by volume. Calculate the range of readings (in volts) of the oxygen sensor in the exhaust stream where there is no combustion (20.9% oxygen in the exhaust system to 5% oxygen in the stream.) (Assume the exhaust is at 600°C. The Universal gas constant = 8.314472J/K/mol. Faradays constant 96487 c/mol.)

(B) Determine if this is a linear or nonlinear sensor in the range tested. (Explain your reasoning.)

A vacuum purging technique is to be used to reduce the oxygen concentration within a cylindrical process vessel with a diameter of 1.5 m and a height of 2.5 m. The oxygen concentration is to be reduced to 0.05 % by volume using nitrogen as the inert gas. The temperature is 20°C and the vessel is initially filled with air. A vacuum pump is used to reduce the pressure in the vessel 75 mm Hg absolute and the vacuum is...

A laboratory procedure is used to measure the level of cadmium in soil. It is applied to a specimen that has a controlled level of 1.5 μg/g of cadmium. Three measurements are obtained by splitting the specimen into three parts of equal weight and applying the procedure to each part. Here are the results: 1.64, 1.85, and 1.94. (a) Does a 95% confidence interval give an indication that the laboratory procedure may be biased? b. What are your assumptions that...
