Dense phase conveying is a term to describe the maximum amount of product that can be moved inside a pipe with the least amount of carrying medium. Typically this is most commonly used in relation to powder forms like cement powder being transferred inside a pipe using compressed air as the fluidizing medium. There is a specific amount of air that can be fed into a powder form that will make the powder flow like water. If you reduce that air amount then compress the powder you can pump it a substantially long way though a pipe with as little as 5% air per volume. Reaching this level is generally known as dense phase transfer.

In a modern industrial plant the most likely polyphase power system in use is a A. one-phase system. C. three-phase system. B. two-phase system. D. four-phase system.?
A "three-phase system" is a polyphase system having three phases. The term "polyphase system" just means a system having multiple phases. If it is used by itself, "a polyphase system" doesn't mean "a three-phase system".
How does a two-phase system differ from a three phase system?
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.
What is Electricity use difference between 3 phase and 1 phase?
A two-phase a.c. system is an archaic system, in which two phase voltages are generated 90 electrical degrees apart. It has nothing whatsoever to do with the US 'split phase' system that supplies North American homes. A two-phase system can be a four-wire system, or a three-wire system, and was useful because, unlike a single-phase system, it could create naturally rotating magnetic fields in induction motors. It has long been superseded by the three-phase system.
How many volts is there in a single phase?
The number of Volts in a residential service drop in the US is either 120V 2 Wire, 120V-208V Network, or 120-240V 3 Wire. A 120-208V Network service is not single phase, but its 120V portion is.
In a three phase power system the phases of each voltages are normally separated by how many time degrees?
In a three phase power system, each phase is separated from the others by 120 degrees.
When sound travels in gas is it more dense or less dense?
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
What phase is water most dense in?
Water is most dense in the heat or hotness
In what phase of matter is water the most dense?
Water is the most dense in its liquid form.
Are gases more dense than liquid?
No. The gas phase is generally less dense than the liquid phase.
What phase is water most dense?
Liquid, buddy.
What phase of water is most dense?
The liquid phase, with 0,9998 g/cm3 at 0 0C.

Why 3 phase ac systems is preferred to 4 phase?
3 phase system has more power than a single phase system
how does pneumatic conveyor works?
Pneumatic conveying systems work by transporting bulk materials such as powders, granules, and pellets through enclosed pipelines using air or other gases as the conveying medium. The process involves several key steps: Material Pickup: The pneumatic conveying system begins by picking up the bulk material from a source point, such as a storage silo, hopper, or material handling equipment. This can be achieved through various methods, including vacuum suction, pressure differential, or mechanical means such as rotary valves or screw feeders. Material Conveyance: Once the material is picked up, it is transported through the conveying pipeline. In dilute phase conveying, the material is suspended within a high-velocity air stream and transported over long distances. In dense phase conveying, the material moves in a slower, denser manner, typically using lower air velocities and higher pressure to minimize particle attrition and maintain material integrity. Air Supply or Vacuum Generation: The conveying air or gas is supplied to the system through an air compressor, blower, or vacuum pump. The air pressure or vacuum level is carefully controlled to provide the necessary force to transport the material through the pipeline at the desired velocity and flow rate. Pipeline Design and Layout: The conveying pipeline is designed to accommodate the specific characteristics of the material being transported, as well as the distance and layout of the conveying route. It may consist of straight sections, bends, elbows, valves, and other components to optimize material flow and minimize pressure drop. Material Separation and Discharge: As the material reaches the end of the conveying pipeline, it is discharged into a receiving vessel or hopper. This vessel may include features such as filters, cyclones, or separators to remove excess air and separate the conveyed material from the conveying air before it is deposited into the final destination. Control and Monitoring: The pneumatic conveying system is controlled and monitored using a control system that regulates the airflow rate, pressure levels, material feed rate, and other parameters. This may involve manual controls, pneumatic or electronic sensors, valves, and programmable logic controllers (PLCs) for automated operation.
