Large, cylindrical bales of hay used to feed livestockin the winter months are D = 2 m in diameter and arestored end-to-end in long rows. Microbial energy gen-eration occurs in the hay and can be excessive if thefarmer bales the hay in a too-wet condition. Assum-ing the thermal conductivity of baled hay to be k =0.04 W/mK, determine the maximum steady-statehay temperature for dry hay (à 1 W/m³), moist hay(4 = 10 W/m³), and wet hay (4 = 100 W/m³). Ambientconditions are T_ = 0°C and h= 25 W/m²K.
