Engineering
HVAC Duct Sizing Calculator
Calculate the required diameter or dimensions of HVAC ducts based on air flow rate and design velocity. Use this when designing ventilation systems to balance air delivery with noise and pressure loss constraints.

Engineering
Column Buckling Calculator
Determines the critical axial load at which a slender column will buckle, using Euler's formula. Use it when designing structural columns in buildings, bridges, or machinery frames to ensure safe load-bearing capacity.
