[Land-speed] Cooling water velocity, was Electric water pumps

Yes, Benn, I am with you. In fact, I think if you look on Stewart water 
pump web site they even explain this ongoing myth. Here is the deal. 
Fast water picks up a littl eheat but since th ewater is flowing so fast 
thenext little increment also picks up the heat until it  all is 
transferred. The system has to be fairly well designed.
