Fitting factor (which takes care of elbows , bends etc) for tubulent flow are readily available. How to get fitting factors when dealing with laminar flow , such as pumping high viscous liquids. I am of the opinion fitting factors in laminar flow will be higher than turbulent flows.

The standard methods for calculating resistance factor values for laminar flow (and also for turbulent flow) at the 2-K (Hooper) and 3-K (Darby) Methods. You will find a thread on this board that discusses this and presents some useful spreadsheets. See
