###### Question:

Consider two blocks A and B that are insulated from all sides except the right side. There is internal heat generation (qa= 104 W/m²) in block A but not in block B. Block B which is in perfect thermal contact with block A is exposed to a fluid at temperature Ta=25C and heat transfer coefficient h= 10 W/m²C. The thickness of block B is LB= 20cm and that of block Ais La=10cm. The thermal conductivity of block B is 5 W/mС. The temperature, To, at the insulated end is measured with a thermocouple after steady state is reached and found to be 175C. insulated insulated 4-0 HT insulated Under steady state conditions • Find the surface temperature of block B, Tes, exposed to the fluid (10%) • Find the interface temperature between block A and B (10%) Find the thermal conductivity of block A (15%)
