An aluminium can (k = 210 W/m.K, ρ = 2700 kg/ m³, C = 900 J/kg.K) having a volume of 350 c m³
contains beer at 1°C. Using lumped system analysis, calculate the time required to reach the beer temperature to 15°C when place in a room at 22°C with h = 15 W/ m².K. Assume (k = 0.66 W/m.K, ρ = 1000 kg/ m³, C = 4200 J/kg.K) and surface area of beer can is 650 cm2.
