Abstract

Settling Times of pressure measuring systems with narrow bore tubing have been computed for the cases when the input pressure varies suddenly and when the input pressure varies linearly with time. Tubing with non-uniform diameter has also been considered, computations employ methods due to Lilley and Morton and Sato. The methods give almost similar results except for large initial pressure rises when Sato's formulation gives higher values for the settling time. Further, the finite difference schemes employed here are explicit in nature and demand less of computer time and memory compared to that used by Sato,
