A plane wall with a surface temperature of 350 degrees Celsius is attached with straight rectangular fins (thermal conductivity k equal to 235 Watts per meter-Kelvin). The fins are exposed to ambient air at 25 degrees Celsius, and the convection heat transfer coefficient is given as h equal to 10 times X Watts per meter squared-Kelvin. Each fin has a length of 50 millimeters, a base thickness of 5 millimeters, and a width of 100 millimeters. Given that X = 6: Determine: a) The heat transfer rate b) The temperature at x equals 25 millimeters c) The temperature at x equals 50 millimeters
