This is a Positive Air Pressure Attenuator (P.A.P.A.). It is a device that can handle Positive Air problems that occur in the Drain, waste and Vent system in a large building. The 3 things to remember about a P..A.P.A is the are much larger than Air Admittance Valves. Secondly They cost a lot more, and lastly they work. The best why to narrow down problems with the DWV system is with a manometer and remembering that a trap can handle 2" of Hg variations.

Key items to keep in mind for atmospheric vent pipelines (e.g. for air, Nitrogen, steam): 1️⃣ discharge at safe location - atleast 5 mt height at top platform, directed outward 2️⃣ bevelled / 45 deg bend at open end (velocity / sound / vibration reduction) 3️⃣ bird screen 4️⃣ proper support to avoid vibration during discharge 5️⃣ weep hole or drain pipe at bottom for draining rain water / condensate if any (to avoid corrosion)

How to find pump discharge? To find pump discharge, you'll typically need to know the pump's flow rate (Q), pressure head (H), and the specific gravity of the fluid being pumped (SG). You can use the following formula: Discharge (Q) = Flow rate (Q) / (Specific gravity of the fluid (SG) * Pressure head (H)) Make sure all units are consistent (e.g., flow rate in m^3/s, pressure head in meters, specific gravity is dimensionless). This formula will give you the discharge in volume per unit time (e.g., m^3/s).

Centrifugal compressor surge is a critical phenomenon that can significantly impact the performance and safety of compression systems. Understanding surge, its causes, effects, and prevention methods is crucial for maintaining safe and efficient compressor operation. Today's blog delves into what centrifugal compressor surge is, its causes and effects, a typical surge curve, and surge control. #surge #prevention #compressor #oilandgastech

The choice of compressor type depends on the required pressure to be obtained. Let's review the relationships between the out pressure and suction rate shown below.

Vacuum Relief/Air Inlet Valves are normally closed. If the system pressure becomes negative, the Vacuum Relief/Air Inlet Valve will immediately admit air into the system and prevent a vacuum from forming. When system pressure returns to positive, the Vacuum Relief/Air Inlet Valve closes air tight.

High thermal conductivity makes water-based liquid cooling popular. Water also has a specific gravity of 1, which helps in the calculations for heat transfer potential. https://ow.ly/ckXB50PXL0e
