Consider an infinitely long rectangular fin exposed to a surrounding fluid at a constant temperature T_a=27°C. The steady state one dimensional energy balance on an element of the fin of thickness dx at a distance x from its base yields d²θ/dx²=m²θ where θ=T_x-T_a. T_x is the temperature of the fin at the distance x from its base in °C. The value of m is 0.04 cm^-1 and the temperature at the base is T₀=227°C. The temperature (in °C) at x=25 cm is _______ (round off to 1 decimal place).
