Question

3. (15) (a) An oxygen sensor is used to measure the ratio of the oxygen concentration level in the air to that in the combustion stream in an internal combustion engine. Assume the concentration of oxygen in the air is 20.9% by volume. Calculate the range of readings (in volts) of the oxygen sensor in the exhaust stream when there is no combustion (20.9% oxygen in the exhaust stream) to 6% oxygen in the stream. (Assume the exhaust is at 650°C. The universal gas constant 8.314472 J/K/mol. Faraday's constant 96,487 C/mol) 5) (bj Determine if this a linear or nonlinear sensor in the range tested. (Explain your easoning)
