Colebrook Equation no solution found

Can someone please explain to me why Mathcad Prime 2 cannot find a solution. I did the same in Mathcad 15 and had no problems. If you add units this makes the situation even worse for MC P2 i.e it complains that it cannot resolve the units. Have I overlooked an otherwise obvious detail?

Regards, Mark

Yes. You've called the function with the parameters in the wrong order! The function is constructed with Re last. You've called it with Re first.
