Incorrect Incorrect 1. Consider an opaque horizontal plate that is well insulated on its backside. The irradiation on the plate is 3000 W/m2, of which 600 W/m² is reflected. The plate is at 150°C and has an emissivity of 0.5. Air at 30°C flows over the plate with a heat transfer convection coefficient of 20 W/m²K. Answer questions 1.1 to 1.3: Question 1 1.1) Determine the absorptivity of the plate: 0.8 Correct Question 2 1.2) Determine the net radioactive flux from the plate, W/m². 1,507.64 Wrong Question 3 1.3) What is the net heat transfer rate per unit area, W/m²? 307.64 Wrong
