A stainless steel rod (AISI 304) of length L = 100 mm and triangular cross section is attached between two isothermal heat sinks at T(x = 0) = T(x = L) = 50°C. The rod perimeter is P = 4.25 mm. When an unknown fluid at T = 23°C is in cross flow over the rod, the temperature of the rod midway between its two ends is measured to be T(x = 0.5L) = 25°C. Determine the value of the convection heat transfer coefficient, in W/m2.K, and the rate of heat loss from the rod, in W. Evaluate the properties of the stainless steel at T = 310 K. h W/m².K W

Question
Transcribed Image Text:A stainless steel rod (AISI 304) of length L = 100 mm and triangular cross section is attached between two isothermal heat sinks at
T(x = 0) = T(x = L) = 50°C. The rod perimeter is P = 4.25 mm. When an unknown fluid at T = 23°C is in cross flow over the
rod, the temperature of the rod midway between its two ends is measured to be T(x = 0.5L) = 25°C. Determine the value of the
convection heat transfer coefficient, in W/m2.K, and the rate of heat loss from the rod, in W. Evaluate the properties of the stainless
steel at T = 310 K.
