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 (a) dry hay (q˙= 1 w/m3 ), (b) moist hay (q˙= 10 w/m3 ), and (c) wet hay (q˙= 50 w/m3 ). ambient conditions are [infinity] t[infinity]= 0°c and h= 25 w/m2·k.
