To maximize production and minimize pumping costs, crude oil is heated to reduce its viscosity during transportation from a production field. (1) Consider a pipe-in-pipe configuration consisting of concentric steel tubes with an intervening insulating material. The inner tube is used to transport warm crude oil through cold ocean water. The inner steel pipe (k, = 45 W/m-K) has an inside diameter of D;, 1 150 mm and wall thickness f; = 20 mm while the outer steel pipe has an inside diameter of D; 2 = 250 mm and wall thickness t, = tị.

The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it?

QUESTION 2 Thermocouples are devices used to measure temperature of a given sample or the surrounding medium. These devices feature a "bead", which has a spherical shape, and produces voltage upon change in temperature. For an engineering application at a pharmaceutical company, thermocouple devices are being tested for their responsiveness, i.e. how fast it can detect temperature changes in the environment (surrounding air). The engineers at this company have specified design constraints for an ideal thermocouple: it must detect temperature changes no later than 1.5 minute, and the reported temperature value must be reasonably correct: at most %3 difference between measured and actual temperature values is allowed. Four thermocouples from different vendors are being tested. Relevant properties of these devices are listed below: Thermal conductivity Density 36 W/m*K 36 W/m*K 42 W/m*K 33 W/m*K Specific Heat 140 kJ/kg*K 120 kJ/kg*K 150 kJ/kg*K 160 kJ/kg*K Device Bead Diameter…
Using the information in Problem 1.22, estimate the ambient air temperature that could cause frostbite on a calm day on the ski slopes. 1.22 In order to prevent frostbite to skiers on chair lifts, the weather report at most ski areas gives both an air temperature and the wind-chill temperature. The air temperature is measured with a thermometer that is not affected by the wind. However, the rate of heat loss from the skier increases with wind velocity, and the wind-chill temperature is the temperature that would result in the same rate of heat loss in still air as occurs at the measured air temperature with the existing wind. Suppose that the inner temperature of a 3-mm-thick layer of skin with a thermal conductivity of 0.35W/mKis35C and the air temperature is 20C. Under calm ambient conditions the heat transfer coefficient at the outer skin surface is about 20W/m2K (see Table 1.4), but in a 40-mph wind it increases to 75W/m2K. If frostbite occurs when the skin temperature drops to about 10C, do you advise the skier to wear a face mask? What is the skin temperature drop due to the wind?

A thermostat control with dial markings from 0 to 100 is used to regulate the temperature of an oil bath. A calibration plot on logarithmic coordinates of the temperature, T (°F), versus the dial setting, R, is a straight line that passes through the points (R1 = 20.0, Ti =110.0 °F) and (R2 = 40.0, T2 = 250.0 °F). (a) Derive an equation for T (°F) in terms of R. (b) Estimate the thermostat setting needed to obtain a temperature of 320°F.
Discussion: 1) discuss the methods of temperature measurement. 2) What is the reference of thermometers calibration tool? 3) What is the meaning of the temperature? What its units? 4) What is the faster method of temperature measurement? 4) Do you have another method or appearance that may be used temperature measurement?
