Here’s a ready-to-post LinkedIn or forum-style post about , optimized for the keyword “scrubber design calculation excel hot”:

where Vg is the gas velocity (m/s or ft/s)

where v is the superficial gas velocity ( typically 1-3 m/s).

: Inlet gas temperature, pressure, and moisture content (lb water/lb dry gas).

A more robust Excel formula using the : $$ \Delta P \approx \fracu_t^2 \rho_g A_t^0.1331270 \times \left( L/G \right) $$ (Note: Ensure consistent units: Pa or in. w.c.)

allows engineers to quickly iterate through design variables like gas flow rates, temperature, and pressure drops to find an optimal configuration. 1. Define Design Inputs and Gas Conditions
