Abstract:
1. A pipe for a fluid serpentine reactor said pipe having individually or in co-operative arrangement an internal flow passage having a continuously smooth and differentiable perimeter and centerline and a smoothly varying cross-section along the flow passage such that in the about 5% of the flow passage from the inlet and the outlet of each pipe the ARQ is from about 1.0 to about 1.02 and over the remaining about 90% of the length of the flow passage not less than about 5% of the flow passage has an ARQ is from about 1.02 to about 1.15, where ARQ is defined as the ratio of aspect ratio (AR) to isoperimetric quotient (Q) of a section or segment of the flow passage perpendicular to the direction of flow (AR/Q) and further where AR=Long/Short and Q=4πA/L 2 where A is area of a cross section of the flow path and L is the perimeter.
