Minor losses in fittings

Little reliable information is available on the pressiue drop for the flow of non-Newtonian fluids through pipe fittings. The limited work carried out on the 

Some guidelines for the design and selection of valves for pseudoplastic materials have been developed by De Haven [1959] and Beasley [1992].

The flow of non-Newtonian fluids in circular and non-circular ducts encompassing both laminar and turbulent regimes is presented in Chapter 3. Issues relating to the transition from laminar to turbulent flow, minor losses in fittings and flow in pumps, as well as metering of flow, are also discussed in this chapter.
