Correction: At 31:50, the viscosity of water at 330 K should be 489E-6 N s/m^2. The viscosity of water at 325 K is 528E-6 N s/m^2 (the entries for viscosity at 325 K and 330 K are next to each other in the thermodynamic property table). Professor Biddle accidentally wrote 528E-8, but used 528E-6 in calculating the Reynolds number. [Time stamps ...
