Prandtl number water table

For most gases over a wide range of temperature and pressure, Pr is approximately constant. Therefore, it can be used to determine the thermal conductivity of gases at high temperatures, where it is difficult to measure experimentally due to the formation of convection currents. Typical values for Pr are: • 0.003 for molten potassium at 975 K WebWater is a less efficient conductor of heat, with Pr = 7, as well as viscous oils, whose Prandtl number is much higher, and can reach 100,000 for heavy oils, which means that heat is …
