The usual effect of elbows, bends, or other obstructions on the flow of liquids in pipes is to lower the critical velocity so that a fluid flowing streamline in a straight pipe may become turbulent upon traversing a bend, or existing turbulence may be increased. In bends or elbows, the degree of turbulence is altered by any change in the ratio of the radius of curvature, R, to the pipe diameter, d. Tests have indicated that the amount of increase in turbulence depends upon the properties of the fluid itself and is not constant for all fluids.
