Medium
For the same plate (20mm thick, 80 MW/m³ generation, faces at 160°C and 120°C, k=200 W/mK), the maximum temperature within the plate in °C is
- A160
- 165
- C200
- D250
Explanation
Using T(x)=−200,000x²+2000x+160 (from the constants found for this plate) at x=0.005m: T=−200,000(0.000025)+2000(0.005)+160=−5+10+160=165°C.
