• SP = Static pressure (in inches of water column, "wc)
• PD = Pressure drop

Ductwork: Friction losses in straight runs and dynamic losses in fittings. Terminal Devices: Grilles, diffusers, and louvers. The Story: 📎 Download the Excel Sheet here:

Part 8: Real-World Case Study – Fixing Static Pressure with Excel

Problem

A hospital RTU delivers 8,000 CFM instead of 10,000 CFM. The maintenance team replaced filters but no improvement. SP = Static pressure (in inches of water

Excel Sheet Input (simplified):

An External Static Pressure (ESP) calculation sheet in Excel is an essential tool for HVAC engineers to determine the resistance a fan must overcome to deliver the required airflow through ductwork and accessories. Core Features of an ESP Excel Sheet

• Preloaded standard pressure loss tables for common components
• Drop-down selections for filters, coils, and fittings
• Automatic sum for supply / return / total ESP
• Built-in check to compare with fan-rated ESP

Recommendation: Use Excel for systems up to 10,000 CFM and 30 branches. For hospitals or labs with 100+ branches, use dedicated software like Revit or Trane Duct Designer.
