Study Notes
Bernoulli Principle
- States that as the speed of a fluid increases, the pressure decreases.
- Fluids flow from high pressure to low pressure in a closed system.
Gas Flow Rates
- Measured in: volume/time.
Fluid Flow Rates
- Expressed in gpm (gallons per minute), gpd (gallons per day), bph (barrels per hour), bpd (barrels per day).
Steam Flow Rates
- Calculated and read in: pounds
Flow Path
- A smooth, obstruction-free flow path is called laminar flow.
- Turbulent flow is caused by obstructions, changes in pipe size or direction, high velocity, or rough pipe interiors.
Flow Measuring Devices
- The most commonly used flow measuring device in industry is the orifice plate.
- Orifice plates create a restriction in the flow path.
Orifice Plate & Flow Velocity
- As flow passes through an orifice plate, its velocity increases.
Delta P Transmitter Reading "Zero"
- A delta P transmitter reading "zero" d/p indicates no flow through the sensor.
