The Prandtl number, Npr, is a dimensionless group important in heat transfer calculations. It is defined as CPµ/k, where CP is the heat capacity of a fluid, µ is the fluid viscosity, and k is the thermal conductivity. For a particular fluid, Cp = 0.583J/(g ∙ ◦C), k = 0.286 W/(m ∙ ◦C), and µ = 1936lbm/(ft ∙ h) Estimate the value of Npr without using a calculator (remember, it is dimensionless), showing your calculations; then determine it with a calculator.
