Large, cylindrical bales of hay used to feed livestock in the winter months are D=2m 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=0.04W/m*K, determine the maximum steady-state hay temperature for dry hay (q, dot = 1W/m^3), moist hay (q, dot= 10W/m^3), and wet hay (q, dot= 100W/m^3). Ambient conditions are T inf =0 C and h = 25 W/m^2*K
Q:Identify where the maximum temp is. Compute this temperature for the wet and dry hay

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
