Duct Static Pressure Calculation: Static Pressure Explained & Step-by-Step Calculation Guide

See all my online courses here: https://course.aircondlounge.com In this video, I explain about static pressure in air conditioning and ventilation duct. I provide multiple examples to show how to calculate the friction loss in duct, the dynamic loss of duct fittings and the pressure drop in various equipment including grille and damper. 0:00 Introduction 0:17 What is Static Pressure 1:46 Components Lead to Pressure Loss 3:59 How to Calculate Duct Friction Loss 7:08 Darcy Equation 11:13 How to Calculate Fitting Dynamic Loss 11:35 Duct Transition (Exhaust/Return) 14:41 Duct Elbow 16:27 Tee Branch 18:20 Duct Transition (Supply) 19:09 Total Friction & Fitting Loss 20:21 Equipment Pressure Drop 22:08 Exhaust Grille 23:32 External Louver 24:26 Non-Return Damper 25:26 Total Pressure Loss & Fan ESP
