single-phase flow. [′siŋ·gəl ¦fāz ′flō] (chemical engineering) The flow of a material, as a gas, single-phase liquid, or a solid, but not in any combination of the three.

Single phase and three phase underground cables. Most high-voltage underground electricity cables are three-phase. ... In current terms, the current that flows out in one conductor flows back in the other, which means it is more naturally described as "single phase".

The definition of the three-phase power supply is, the power flows through three conductors. ... Single phase requires the single wire to connect the circuit whereas; 3-phase needs 3-wires. The voltage of the single phase is 230V, whereas three phase voltage is 415V.

An Oscillating Heat Pipe (OHP), also known as a Pulsating Heat Pipe (PHP), is a two-phase heat transfer device that was invented by Akachi in the1990s [1], [2]. An OHP only consists of a bended capillary tube and the working fluid in it, as shown in Fig. ... This is the basic principle of heat transport for an OHP.

The operation principle of the single-phase transformer is: the AC voltage source injects the AC current through the transformer primary winding. The AC current generates the alternating electromagnetic field.

A Single Phase Induction Motor consists of a single phase winding which is mounted on the stator of the motor and a cage winding placed on the rotor. ... Under these conditions, the rotor of an induction motor does not rotate. Hence, a single phase induction motor is not self-starting.

Ebb and Flow (also called Ebb flood and flood drain) are two phases of the tide or any similar movement of water. The Ebb is the outgoing phase, when the tide drains away from the shore; and the flow is the incoming phase when water rises again. The terms are also common in figurative use.

Internal and External flow: The flow of an unbounded fluid over a surface is treated as 'external flow' and if the fluid is completely bounded by the surface, then it is called as 'internal flow'. For example, flow over a flat plate is considered as external flow and flow through a pipe/duct is internal flow.

A single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy. It works by using a single-phase power supply. They contain two types of wiring: hot and neutral. Their power can reach 3Kw and supply voltages vary in unison.

bulk flow. "Bulk flow" is the movement/flow of an entire body due to a pressure gradient (for example, water coming out of a tap). "Diffusion" is the gradual movement/dispersion of concentration within a body, due to a concentration gradient, with no net movement of matter.

Laminar and turbulent flow. Laminar flow or streamline flow in pipes (or tubes) occurs when a fluid flows in parallel layers, with no disruption between the layers. ... Turbulent flow is a flow regime characterized by chaotic property changes. This includes rapid variation of pressure and flow velocity in space and time.

Single Phase Preventer Working Principle: Single phase preventer is used to protect the induction motor from single phasing fault. ... Generally single phasing is nothing but a motor runs when one of the supply is disconnected due to open circuit or improper contact in switch or other electrical equipment failure.

The main difference between single phase induction motor and three phase induction motor is that single phase motors are NOT self-starting so they require some starting mechanism while three-phase motors are self-starting.

Single phase UPS have a single input and output source to the electrical equipment. With just one sinewave voltage, it only requires two wires to complete the circuit, one conductor and one neutral.

Single-pipe system: The single-pipe, non-direct vent system is used where there is no real need for a separate combustion air intake vent. It provides a vent pipe for exhaust gases but uses unconditioned (not cooled or heated) air from the space around the furnace for combustion air.

Single-phase power is a two-wire alternating current (ac) power circuit. Typically, there is one power wire—the phase wire—and one neutral wire, with current flowing between the power wire (through the load) and the neutral wire. ... three-phase is that a three-phase power supply better accommodates higher loads.

Flow is steady when the velocity at any point of observation does not change with time; if it changes from instant to instant, flow is unsteady. At every instant, if the velocity is the same at all points along the channel, flow is uniform; if it is not the same, flow is nonuniform.
