Question: The Prandtl number, NPr, is a dimensionless group important in heat-transfer calculations. It is defined asC p /k, where C p is the heat capacity

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