Heat Q, which has the SI unit of joule (J), is the quantity in mechanical engineering that describes the transit of energy from one location to another. The equation for the flow of heat during the time interval At through an insulated wallisKAATQ =(Тh — T)where k is the thermal conductivity of the material from which the wall is made, A and L are the wall's area and thickness, and Th – T; is the difference (in degrees Celsius) between the high- and low-temperature sides of the wall. Byusing the principle of dimensional consistency, what is the correct dimension for thermal conductivity in the SI? The lowercase Greek character kappa (K) is a conventional mathematical symbol used for thermal conductivity. Appendix Asummarizes the names and symbols of Greek letters.О a.

The quantity of energy Q transferred by heat conduction through an insulating pad in time interval Δt is described by Q/Δt = κAΔT/d, where κ is the thermal conductivity of the material, A is the face area of the pad (perpendicular to the direction of heat flow), ΔT is the difference in temperature across the pad, and d is the thickness of the pad. In one trial to test material as lining for sleeping bags, 86.0 J of heat is transferred through a 3.40-cm-thick pad when the temperature on one side is 37.0°C and on the other side is 2.00°C. In a trial of the same duration with the same temperatures, how much heat will be transferred when more of the material is added to form a pad with the same face area and total thickness 8.41 cm?
An engineer who is working on the heat transfer analysis of a house in English units needs the convection heat transfer coefficient on the outer surface of the house. But the only value he can find from his handbooks is 22 W/m2·K, which is in SI units. The engineer does not have a direct conversion factor between the two unit systems for the convection heat transfer coefficient. Using the conversion factors between W and Btu/h, m and ft, and °C and °F, express the given convection heat transfer coefficient in Btu/h·ft2·°F.
The quantity of heat Q that changes the temperature ΔT of a mass m of a substance is given by Q=c⋅m⋅ΔT, where c is the specific heat capacity of the substance. For example, for H2O, c=1 cal/(g⋅°C). And for a change of phase, the quantity of heat Q that changes the phase of a mass m is Q=mL, where L is the heat of fusion or heat of vaporization of the substance. For example, for H2O, the heat of fusion is 80 cal/g (or 80 kcal/kg) and the heat of vaporization is 540 cal/g (or 540 kcal/kg). Use these relationships to determine the number of calories to change 0.60 kg of 0°C ice to 0.60 kg of 100 °C steam.
