2.26. The Prandtl number, Npr, is a dimensionless group important in heat-transfer calculations. It is defined as Cpulk, where C, is the heat capacity of a fluid, u is the fluid viscosity, and k is the thermal conductivity. For a particular fluid, C, = 0.583 J/(g-°C), k = 0.286 W/(m-°C), and u = 1936 lbm/(ft-h). Estimate the %3D value of Npr without using a calculator (remember, it is dimensionless), showing your calculations; then determine it with a calculator.
