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 SPPU TE Mechanical – HMT Unit 4: Radiation (Theory + Numericals) This video explains Radiation Heat Transfer for end-sem exams, including all important SPPU pattern numericals such as emissive power, shape factor, radiation exchange between surfaces, blackbody concepts, gray body, and radiation shields. What’s included: ✔ Radiation basics & laws (Stefan–Boltzmann, Kirchhoff, Planck) ✔ Blackbody, gray body & real-surface properties ✔ Shape factor (View factor) formulas & solved sums ✔ Enclosed surface radiation problems ✔ Radiation shield numerical examples ✔ Important end-sem theory points ✔ TE Mechanical exam-oriented shortcuts ✔ Mistakes students commonly make in Unit 4 If this video helps you — LIKE, SHARE & COMMENT your next HMT unit request. #hmt #radiation #HMTUnit4 #SPPUTEMechanical #TEMechanical #heattransfer #RadiationHeatTransfer #engineeringstudents #mechanicalengineering #exampreparation #sppu #endsemprep #thermalengineering #solvednumericals Join our “Mature Engineers” WhatsApp Group! https://chat.whatsapp.com/LrtOCWG7hFS...
