What is constant if flow through a Prandtl-Meyer expansion wave?
The flow's Mach angle is constant through a Prandtl-Meyer expansion wave.
What is the Graetz number?
The Graetz number is {(Diameter/Length)*Reynolds#*Prandtl#}^(1/3) It is used to characterize the thermal development of pipe flow: if the Graetz number is less than 1000, the thermal profile is fully developed.
A dimensionless number which is a ratio of kinematics viscosity to thermal diffusivity is known as?
The Prandtl Number is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) and thermal diffusivity and can be expressed asPr = v / αThe Prandtl number can alternatively be expressed asPr = μ cp / kThe Prandtl Number is often used in heat transfer and free and forced convection calculations. where:ν : kinematic viscosity, ν = μ / ρ, (SI units : m2/s)α : thermal diffusivity, α = k / (ρcp), (SI units : m2/s)μ : dynamic viscosity, (SI units : Pa s)k: thermal conductivity, (SI units : W/(m K) )cp : specific heat, (SI units : J/(kg K) )ρ : density, (SI units : kg/m3 ).answered by : eng_moom
When was the centrifuge invented?
The centrifuge was first invented in the late 19th century, with the first patent for a centrifugal separator being filed in 1864 by Antonin Prandtl. However, the modern centrifuge as we know it today, with improvements in design and functionality, was developed in the early 20th century.
