Booster Pump System – Basic Understanding for Engineers & Technicians.

Gul Bahar Shah
  Booster Pump System – Basic Understanding for Engineers & Technicians. My First Knowledge Sharing Post – Booster Pump System As part of my work in Facility Management, I’m starting to share practical engineering knowledge that we use daily on site. #FacilityManagement #MEP #Engineering #BoosterPump #WaterPressure #Maintenance #Learning #SaudiArabia #TechnicalKnowledge . Booster Pump System plays a key role in maintaining stable water pressure in buildings. It consists of: Booster Pumps Bladder Tank MCC Panel (Automatic Control) This system helps in: ✔ Maintaining consistent water pressure ✔ Reducing pump wear & energy consumption ✔ Improving overall system efficiency

External Static Pressure (ESP) in HVAC Systems,

Gul Bahar Shah
External Static Pressure (ESP) in HVAC Systems,
Calculating External Static Pressure (ESP) in HVAC ducts is an integral aspect of system design and maintenance.
 Adhering to ASHRAE standards ensures proper airflow, efficient operation, and optimal performance of HVAC systems in various spaces.
🔹ESP, in short, is the pressure that the fan needs to push the air and overcome all the obstacles.
🔹 Why ESP Matters:
❌ Too low ESP: Air won’t reach all areas properly
⚠️ Too high ESP: Higher energy consumption
✅ Balanced ESP: Ensures proper airflow, efficiency & optimal fan performance
👉Static Pressure (SP): Resistance in the system air flow (measured perpendicular to airflow). Can be positive or negative depending on Fan placement. Its determines fan capacity
👉Velocity Pressure (VP): Pressure from air motion (parallel to airflow), representing kinetic energy. supports duct design using methods such as Equal Friction and Static Regain.
⚙️ ESP Calculation = Straight Duct friction Loss+ Fittings Loss+ Device Loss
➡️ Straight Duct Loss: Length (m) × Friction Loss (Pa/m)
🧹 Fittings Loss: From ASHRAE Duct Fittings Data Sheets (reducers, elbows, tees, etc.)
 💨 Device Loss: From manufacturer data or ASHRAE (diffusers, grilles, dampers, louvres)

Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries

Gul Bahar Shah
Cathodic Corrosion Protection Systems Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries Preface Contents Preface The oil and gas industry depends on steel and other metals for pipelines, storage tanks, and infrastructure. However, these metals can corrode when exposed to water or soil, which is detrimental to the integrity of pipelines and storage tanks. This engineering book outlines the minimum requirements for anodes (high-silicon iron, graphite, magnetite) used in impressed current CP systems. It details the composition, materials, manufacturing, properties, inspection, and testing of these anodes. Additionally, it provides revised survey requirements to ensure corrosion control systems on buried or submerged structures are well-designed, operated, and maintained. The book also covers techniques, equipment, ...
