Consider a conduction in a plane composite wall as shown. The outer hotter air temperature a 60 C whose convective heat transfer coefficient of 1000 W/m² K while the colder side at 24 with heat transfer coefficient of 750 W/m² K. There is 5 C drop of temperature between air an wall surface at both hotter and colder side. The temperatures at the interfaces are 45 C and 4 C. Find the thermal conductivity of wall B. Hot air A B -2LB KA = 25 W/m-K kc = 50 W/m-K C 4k LA = 30 mm LB = 30 mm 30 mm Cold air

Type in your answer/s rounded off to 2 decimal places except for whole numbers. (ex: 10.67, 28, 732.40) If your answer is 120.00 kN, just write 120 kN Do not round off values during solving. Use the store function of your calculator or its fraction if applicable. Include the units after your answer. Leave a space between the value and the unit. (ex: 6323.17 m, 73.10 rad/s^2, 100 kN) For stresses, type (C) for compression and (T) for tension one space after the unit. (ex: 18.19 MPa (C), 6.88 psi (T))
