The Prandtl number, Npr, is a dimensionless group important in heat transfer calculations. It is defined as Cpf-L/ k, where Cp is the heat capacity of a fluid, f-L is the fluid viscosity, and k is the thermal conductivity. For a particular fluid, Cp = 0.583 J/(g'0C), k = 0.286 W/(m.0C), and f-L = 1936 lbm/(fth). Estimate the value of NPr without using a calculator (remember, it is dimensionless), showing your calculations; then determine it with a calculator.
Chapter 17: Aspects of Aqueous Equilibria Strong electrolytes exist as separate ions in solution The Common-Ion Effect Consider a solution of acetic acid If acetate ion, CH COO , is added to the solution, LeChatelier says the 3 equilibrium will shift to the left, meaning the formation of acetic acid will be favored and the H concentration will decrease “The extent of ionization of a weak electrolyte is decreased by adding a strong electrolyte to solution that has an ion in common with the weak electrolyte” Common ion equilibrium problems are solved similarly to other equilibrium problems (ICE tables) However, the initial concentration of the common ion (from the salt) must be considered Buf
