- 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?Newton's Law of cooling states that the rate at which heat is lost by a heated body is proportional to the difference in temperature between the body and the surrounding medium. Match the following statements/phrases with the corresponding item in the drop down box. Choices in the box 1. In accordance with the stated law obove, we have the equation? 2. If a thermometer is taken outdoors where the temperoture is 5 deg C, from a room in which the temperature is 20 deg C and the reading drops 10 deg C in one minute, the working equation is? 3. In the obove problem, separoting the variables and integrating will result to? 4. In the obove problem, how long, in minutes, after its removal from the room will the reading be 6 deg C? 5. In the obove problem, ofter 30 seconds, whot will be the thermometer reading? 5.2 dT(body temp)/dt = k(Temp of medium - 5) dr(body temp)/dt = k(Temp of body - Temp of medium) Temp of body = Cenkt +5 2.5 13.7 dr(body temp)/dt = k(Temp of medium - Temp of body)…Considering the transportation costs of natural gas over land by pipeline, natural gas specifications can be relaxed.

- A heat pump is an electrical device that heats a building by pumping heat in from the cold outside. In other words, it's the same as a refrigerator, but its purpose is to warm the hot reservoir rather than to cool the cold reservoir (even though it does both). Let us define the following standard symbols, all taken to be positive by convention:Th = temperature inside buildingTe = temperature outsideQh heat pumped into building in 1 day Qe = heat taken from outdoors in 1 dayW = electrical energy used by heat pump in 1 day Explain why a heat pump is better than an electric furnace, which simply converts electrical work directly into heat. (Include some numerical estimates. )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…APPLICATIONS OF FIRST ORDER DIFFERENTIAL EQUATIONS Newton’s Law of Cooling and Joint Proportions At 4:00pm, a thermometer reading of 28 deg C is taken outside where the ambient temperature is –11 deg C. At 4:05 pm, the thermometer reads 8 deg above zero. After a while, the thermometer is returned to the room maintained at 28 deg C. At 4:12pm, the thermometer reads 15 deg C. When was the thermometer returned to the room?
