HMT Unit 4 – Radiation | SPPU TE Mechanical | Full Numericals

Описание: Question
Two large parallel plates are maintained at temperatures of 600 °C and
300 °C having their emissivity’s of 0.9 and 0.4 respectively. A radiation
shield having emissivity of 0.02 is inserted in between them. Calculate[10]
i) Heat transfer rate without shield
2) Heat transfer rate with shield and Use σ = 5.67×10–8W/m2K
3) % of reduction
