Question

A hot titanium solid cube weighing 30kg is submerged in an insulating bath holding 50 L of glycerol are allowed to equilibrate thermally surroundings . Initially, the titanium cube and the glycerol are at 850°C temperature (in °C) of the titanium cube and the oil?

Data: Titanium: p =4500kg/m³ , c= 0.523

kJ/kg.K; glycerol: p= 1260 kg/m³ , c = 2.37 kl/kg.K

Answer 1

30×50×1123/4500×1260

= 0.297
