The prandtl number, pr, is a dimensionless group important in heat transfer. it is defined as pr cp*mu/k = where cp is the heat capacity of a fluid, mu is the fluid viscosity, and k is the fluid thermal conductivity. for a given fluid, cp 0.5 j/(g * deg c), k 0.2 w/(m * deg c), and mu 2200 lbm (ft* h}. determine the value of the prandtl number for this fluid. keep two significant figures in your final answer
