SOLVED: A vertical cylinder 1.5m high and 180 mm in diameter is maintained at 100°C in an atmospheric environment of 20°C. Calculate the heat loss by free convection from the surface of the cylinder. Assume properties of air at mean temperature as p = 1.06 kg/m³, v = 18.97 x 10â»Â³ m/s, c = 1.004 kJ/kg°C, and k = 0.1042 kJ/mh°C.Given:L = 1.5mD = 180mm = 0.18mtâ‚ = 100°Ctâ‚‚ = 20°Cp = 1.06 kg/m³v = 18.97 x 10â»Â³ m²/sc = 1.004 kJ/kg°Ck = 0.1042 kJ/mh°C.

(a) Calculate the heat flux through a sheet of brass 7.5 mm(0.30 in.) thick if the temperatures at the two faces are 150 and 50^∘ C (302 and 122^∘ F ); assume steady-state heat flow. (b) What is the heat loss per hour if the area of the sheet is 0.5 m^2(5.4 ft^2) ? (c) What will be the heat loss per hour if soda-lime glass instead of brass is used? (d) Calculate the heat loss per hour if brass is used and the thickness is increased to 15 mm ( 0.59 in.). | Numerade
