TABLE 7-5 (from Çengel and Cimbala, Fluid Mechanics: Fundamentals and Applications , McGraw-Hill, 2006) Some common established nondimensional parameters or Π s encountered in fluid mechanics and heat transfer; A is a characteristic area, D is a characteristic diameter, f is a characteristic frequency (Hz), L is a characteristic length, t is a characteristic time, T is a characteristic (absolute) temperature, V is a characteristic velocity, W is a characteristic width, is a characteristic power, ω is a characteristic radial frequency or angular velocity (radians/s). Other parameters and fluid properties in these Π s include: c = speed of sound, c p , c v = specific heats, d p = particle diameter, D AB = species diffusion coefficient, h = convective heat transfer coefficient, h fg = latent heat of evaporation, k = thermal conductivity and also k = ratio of specific heats, P = pressure, T sat = saturation temperature, = volume flow rate, α = thermal diffusivity, β = coefficient of thermal expansion, λ = mean free path length, μ = viscosity, ν
