Question

2. A separation column at a temperature of 100C is subjected for cooling for a certain period of time. If the separation column is 1500 mm high and 18 cm in diameter, and eventually exposed to an environment temperature of 35C, determine the following with a neat diagram:

a) Heat Transfer Coefficient (in J/s m2C and kJ/s m2C)

b) Heat transfer Rate (in W and kW)

Assume the properties of air at mean temperature as density (ρ) = 1.06 kg/m3, kinematic viscosity (γ) = 0.0011382 m2/min, specific heat (cp) = 1.004 kJ/kgC and thermal conductivity (k) = 0.1042 kJ/mhC
