Question 3 To determine the temperature of the air in an exhaust duct at full plant operation, forty (40) measurements are taken over a short period of time. The average of the measurements was found to be 1104 °C, and the standard deviation of the sample was 12°C. Determine the 90% confidence interval for the temperature of the air in the exhaust duct during full plant operation.

An ideal heat engine operates in a cycle and produces work as a result of heat transfer from a thermal reservoir at an elevated temperature Tŉ and by rejecting energy to a thermal sink at Tc. The efficiency for such an ideal cycle, termed a “Carnot cycle," is n = 1 Determine the required uncertainty in the measurement of temperature to yield an uncertainty in efficiency of 1%. Assume that errors are uncorrelated. Use Th = 313 K and Tc = 293 K.

The entire apparatus is contained in a water bath to maintain a constant temperature of 25 °C. The piston is released and the gas expands until the pressure inside the cylinder equals the atmospheric pressure outside, which is 1.00 atm. Assume ideal gas behavior and calculate the amount of work done by the gas as it expands at constant temperature.

What does the Dry Bulb Temperature relate to? On a day that it is sunny outside, would you expect the wet and dry bulb temperature to be close to, or far from each other? PART B: If the Dewpoint Temperature and Temperature are far from each other, what does that mean about the relative humidity? On a day that it is raining, would you expect the Dewpoint Temperature and Temperature to be close to each other, or far from each other?
