What factors affect pressure loss?

CHAPTER 4PRESSURE LOSS FACTORS THAT CAUSE “PRESSURE LOSS”

• [1] NARROWING THE PIPE DIAMETER. Restricting the flow path means that piping joints with different diameters will result in pressure loss.
• [2] BENDING THE PIPING.
• [3] INSTALLING AN OPEN/CLOSE VALVE.
• [4] INSTALLING A FLOW METER.

What causes fluctuating water pressure?

When air gets trapped in pipes, it can cause fluctuating, and spluttering water pressure as the air and water move through the pipes. Air can enter the pipes through a leaking suction line, damaged tank bladders, a faulty pump, gas build up in the well system or leaks in the pipeline.

Why does pressure decrease when a pipe narrows?

the Velocity increases and the pressure decreases. This happens because the narrow section is a restriction which causes an increase in pressure in the broader, upstream pipe.

What increases and decreases pressure?

Summary. An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.

What are the two main factors that pressure depend on?

(1)It depends on force applied. (2)Area over in which force acts. The same force can produce different pressure depending upon area in which it acts. When the force acts over a large area,the pressure produced is less.

What does pressure drop in a pipe mean?

The effect of pressure drop on safety Over-pressure situations caused by pressure drop can also lead to safety concerns. Processing systems are designed to operate safely and efficiently. When system piping is undersized for a specific application, the pump has to be oversized to accommodate the pressure drop.

Does decreasing pressure increase reaction?

When you decrease the pressure, molecules don’t hit each other as often and the rate of reaction decreases. Pressure is also related to concentration and volume. By decreasing the volume available to the molecules of gas, you are increasing the concentration of molecules in a specific space.
