Question

10. An iron pan is used to fry a cylindrical piece of meat (mass=0.120kg, 1.50cm thickness and 10.0cm diameter). The temperature of the pan is heated to a constant temperature of 350.0°F. The thermal conductivity of the meat is 0.400W/(mK) and the emissivity of the meat is 0.900. Assume the specific heat capacity of the meat is 3500J/(kg:K). a. After the meat is placed on the pan, the temperature of Troom=70.0°F the contacting surface is raised to a constant temperature of 100.0°C and the opposite face of the meat initially is 10.0cm 5.0°C. Calculate this initial rate of conductive heat flow through the meat. Assume steady-state heat transfer. 1.50cm meat Hot Pan ON
