Temperature related material properties

Temperature-related properties of materials are the properties that change or show any variation with temperature variations. Various properties of materials include physical properties, mechanical properties, chemical properties, electrical properties, magnetic properties, etc. The chemical, electrical, and magnetic properties of materials are important, but the physical and mechanical properties are more important. Based on their composition and chemical bonding, materials are classified as metals, ceramics, polymers, and composites.

Example: A product developer is interested in reducing the drying time of a primer paint. Two formulations of the paint are tested; formulation 1 is the standard chemistry, and formulation 2 has a new drying ingredient that should reduce the drying time. From experience, it is known that the standard deviation of drying time is 8 minutes, and this inherent variability should be unaffected by the addition of the new ingredient. Ten specimens are painted with formulation 1, and another 10 specimens are painted with formulation 2; the 20 specimens are painted in random order. The two sample average drying times are 121 minutes and 112 minutes, respectively. What conclusions can the product developer draw about the effectiveness of the new ingredient, using a-0.05?
A jar test was conducted on a raw water containing 11 NTU and an alkalinity concentration of 50 mg/L (as CACO3). The Turbidity was measured after the mixture was allowed to settle for 30 minutes. The jar test are tabulated below Find the optimal coagulant dose, and the appropriate amount of alkalinity that would be consumed at the optimal dose Does the raw water source have sufficient alkalinity? Jar Numbers 1 2 3 4 5 6 Alum Dose (mg/L) 25 40 50 65 75 Turbidity (NTU) 9 6 2 4.5 5.5 8.5
A step-dose tracer test was conducted on the clear well of a water treatment plant. A constant fluoride dosage of 2.0 mg/l was added at the inlet starting at time zero, and the fluoride concentrations in the outflow were measured and recorded every 5 or 10 min as listed in the following table. Calculate the C/C0 values, plot C/C0 versus t, and determine t10. (Answer t10 = 22 min) HINT: For 7-59, after you plot C/Co vs. time with Co = 2.0 mg/L, to find t10 you look for the value C/Co = 0.1 and this determines t10 on the graph. t10 is the length of time for 10% of the water entering the tank to discharge from the tank. This time is determined by tracer studies.
