Question 3

A sheathed thermocouple is placed in a combustion chamber to measure the temperature of the gases at a certain point in the process. The thermocouple reading is 1110K and the inside wall temperature was measured at 1008K. The thermocouple has a surface area of 10 mm2 .

(a) A pitot probe is used to measure the velocity of the gas stream in the vicinity of the thermocouple tip. It measures a difference in static and dynamic pressure of 10 Pa. The convection heat coefficient (W/m2K) between the hot gases and the thermocouple is given by a correlation:

h = K.u^0.466

where: u is the velocity in m/s

K = empirical constant at high temperature = 50

What is the true gas temperature?

(b) A thermocouple is instead embedded inside the wall of a small conductive tube of inside diameter 20 mm, outside diameter 25 mm and length of 30 mm. The tube and embedded thermocouple are at a uniform temperature of 1110K. Suction is applied to the tube so that hot gas is drawn through the tube at 200 m/s. The heat transfer coefficient between gas and tube can be calculated by the correlation in part (a).

Assume the inside wall temperature of the combustion chamber is still 1008K. What is the true gas temperature? What is the temperature reduction of the gas in passing through the 30mm length of the tube?

Notes:

The Stefan Boltzmann constant is 5.669x10-8 W/m2 .K4 Assume gas density = 0.28 kg/m3 over the entire range of temperatures in this question. Assume gas Cp =1.19 kJ/kg.K over the entire range of temperatures in this question. The emissivity of the thermocouple and radiation shield and combustion chamber walls are all 0.75.

Determine the heating area required for the production of 4535.9 kg/h of 50% NaOH solution from a 10% NaOH feed entering at 37.8oC. Evaporation is to be carried out in a single-body standard evaporator for which an overall coefficient of 2839 W/m2.K is expected. Steam is available saturated at 446.09 kPa and the evaporator can be operated at 32.4kPa. (A = 137.07 m2)

1. a. Assume that Data Set A depicts the scores of 10 subjects who received either Treatment 1 or Treatment 2. Calculate a t-test for independent means to determine whether the means are significantly different from each other. In your complete answer, remember to include your t-statistic, critical value, and your decision about whether to reject the null hypothesis. For this question, you should assume that different participants received the two different treatments.

b. Now assume that Data Set A depicts the scores of five subjects who received both Treatment 1 and Treatment 2. Calculate a t-test for dependent means to determine whether the means for the two treatments were significantly different. The correlation between the two treatments is +1.00. In your complete answer, remember to include your t-statistic, critical value, and your decision about whether to reject the null hypothesis. For this question, you should assume that the same participants received each of the two treatments.

Data set A:

Part 2 (separate program)

Ask for a file name. Don’t let the program crash if you enter the name of a file that does not exist. Detecting this will also be discussed on Wednesday. If the file doesn’t exist gracefully display an error message stating the file doesn’t exist and quit the program. It the file does exist read all the values in the file. You will only need to read the file once, or more to the point, only read the file once. After the program has finished reading all the data, display the following information to the screen:

• The minimum value

• The maximum value

• If any values were 100. No output if no values were 100.

• If any values were 0. No output if no values were 0.

• The average – display with 4 places after the decimal point

• The total number of values

• The total number of values greater than or equal to 75

• The total number of values less than 75

• The value closest to 75 (can be 75, less than 75 or greater than 75). abs will be useful for this value.

• The value closest to 75 WITHOUT going over 75 (can be 75, WILL NOT be greater than 75) If no data exists in the file, write out a simple message indicating that there was no data in the file and nothing else.
