The properties of mercury at 300 K are: Density = 13529 kg/m³, cp = 0.1393 kJ/kgK, dynamic viscosity = 0.1523 × 10^–2 Ns/m² and thermal conductivity = 8.540 W/mK. The Prandtl number of the mercury at 300 K is

1. 0.0248
2. 2.48
3. 24.8
4. 248

Correct Option: A

Prandtl number =	μC_p
	K

= 0.1523 × 10^-2	N_s	×	0.1393 × 1000	kJ	= 0.0248
