1.	Given: cupola diameter = 53cm, mass of bed charge = 465kg, height of groove = 7.2m. Find coke density.(a) 372.72 kg/m^3(b) 292.73 kg/m^3(c) 223.62 kg/m^3(d) 390.57 kg/m^3I have been asked this question during an interview.Question is taken from Coke Bed Charge Calculations topic in portion Metal Furnace and Practice of Casting-Forming-Welding II
Answer» Correct option is (b) 292.73 kg/m^3 The best EXPLANATION: Here, d = 53cm = 0.53m, W = 465kg, HEIGHT of groove, H = 7.2m. Therefore, according to the formula, W = π/4 X d^2 x h x w => w= 465 / (π/4 x 0.53^2 x 7.2) => w = 292.73 kg/m^3.
