K Problem 2 The Prandel number, Npr, is a dimensionless group important in heat transfer calculations. It is defined as com where: Cp is the heat capacity of a fluid, M is the fluid viscosity k is the thermal conductivity Estimate the value of Npr for a particular fluid has the following parameter Cp = 0,583)/(gC), k = 0.286 W/(m. C). 1936 lbm/(ft.h)
