SUMMARY
The K factor for a contraction in fluid dynamics is calculated using the inlet and outlet pressure difference. This involves determining the pressure difference, dividing it by the product of fluid density (rho) and gravitational acceleration (gravity) to find the height (h). The equation h = K (V2/2g) is then rearranged to solve for K. It is essential to use the actual pressure drop compared to the ideal pressure drop to accurately compute h for this calculation.
