Large, cylindrical bales of hay used to feed livestock in the winter months are D =2 m in diameter and are stored end-to-end in long rows. Microbial energy generation occurs in the hay and can be excessive if the farmer bales the hay in a too-wet condition. Assuming the thermal conductivity of baled hay to be k = 0.04 W/m *K, determine the maximum steady-state hay temperature for dry hay (q dot = W/m^3), moist hay (q dot = 10 W/m^3), and wet hay (q dot = 100 W/m^3). Ambient conditions are T inf =0 C and h = 25 W/m^2*K.
