A more impossible equation? LOL
One company says this is the best version of the Colebrook Equations. If you read my last ToM , you can do this one. They say with this version you need to purchase their approximation method. Assume Re =200000 and Rr=0.04 like the other one. Figure to 15 decimals and find out “How much different is there in this F and the last one?”
Does it look harder?
Would you need to buy their approximation?
