Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600°C (-150 to 2900°F) and at pressures ranging 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units.
9 sty 2024 · The Prandtl Number Calculator serves as a tool to determine a crucial dimensionless number in fluid mechanics. This number, named after Ludwig Prandtl, helps in analyzing the relative importance of momentum diffusivity to thermal diffusivity in a fluid.
The Prandtl Number is often used in heat transfer and free and forced convection calculations. It depends on the fluid properties. gases - Pr ranges 0.7 - 1.0 ; dry air ; water - Pr ranges 1 - 10 ; liquid metals - Pr ranges 0.001 - 0.03 ; oils - Pr ranges 50 - 2000 ; Example - Calculation of a Prandtl Number. μ = 15 (cP) c p = 0.50 Btu/(lb m o F)
Formula for the calculation of the Prandtl number of air and water. For air with a pressure of 1 bar, the Prandtl numbers in the temperature range between −100 °C and +500 °C can be calculated using the formula given below. [ 2 ] The temperature is to be used in the unit degree Celsius.
Get ready to dive into the world of fluid dynamics with our Prandtl Number Calculator! Ever wondered how efficiently heat is conducted in different fluids? Let’s uncover the secret behind it, and no, it’s not magic—it’s the Prandtl Number!
PYroMat is an expanding and all-python open source property calculator. The Industrial Refrigeration Consortium is a collaborative effort between the University of Wisconsin-Madison and industry. Our goal is to improve the safety, efficiency, and productivity of industrial refrigeration systems and technologies.
The prandtl number of air is around 0.7 as many other gases at 1 atm. The Prandtl Number is a dimensionless number approaching the proportion of momentum diffusivity and thermal diffusivity. Prandtl number equation is defined as:
