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.arrow_forward
- How much in peso is the cost of boiling 13.2 L of water from 22 °C using a heavy cook pot with mass of 3.27 kg and with specific heat capacity of 512 J/Kg-C° if the cost of energy is 14.60 pesos per kilowatt-hour? NOTE: Specific heat capacity of water is 4186 J/Kg- C° . Round off answer up to 2 decimal places. Input only the numerical value of the answer.arrow_forwardHeat 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 wall is KAAT Q = (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. By using 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 A summarizes the names and symbols of Greek letters. О a. (W-m)/°C O b. °C/(W. m) O c. (m . °C)/W O d. W/(m . °C)arrow_forwardThe 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.arrow_forward
