The market report categorizes oil and gas equipment under two broad classifications: static equipment and rotating equipment. Oil and gas static equipment comprise valves, boilers, furnaces, heat exchangers, and others. Oil and gas rotating equipment comprise turbines, pumps, compressors, and others.

The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.

An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed and the magnet usually moves. ... The two backup generators are used for different purposes.

The centrifugal pumps work on the centrifugal action of rotating impeller to push the fluid. ... The main difference between the centrifugal pumps and positive displacement pump is that positive displacement pumps moves fluid at the same speed regardless of the pressure on the inlet end and centrifugal pumps will not.

Static risks are those which would exist in an unchanging world. ... Conversely, dynamic risks are those risks which result from change itself. Dynamic risks may rise from significant changes in the frequency or severity of existing sources of loss or from completely new sources.

Static calibration utilizes reference values which do not change with time. ... Dynamic calibration has reference values which change with time and you measure the response as it also changes with time.

Static balancing uses one set of wheel weights in the centre of a wheel whereas, Dynamic balancing uses two sets of weights. ... You may be able to get the display on a wheel balancer to show zero on its imbalance reading. But this does not mean the wheel is balanced correctly, far from it!

The main difference between them is in regard to what spins and what is fixed. 1. In an alternator, electricity is produced when a magnetic field spins inside the stator (windings of wire). In a generator, on the other hand, the armature or windings of wire spin inside a fixed magnetic field to generate electricity.

Static balance refers to the ability of a stationary on object to its balance. This happens when the objects centre of gravity is on the axis of rotation. Whereas dynamic balance is the ability of an object to balance whilst in motion or when switching between positions.

Static pressure is the pressure you have if the fluid isn't moving or if you are moving with the fluid. ... Total pressure is what acts on you as you face into the wind and the air collides with your body. Dynamic pressure is the pressure of a fluid that results from its motion.

The Difference Between the Two With both static and dynamic exercises, little or no special equipment is needed. The difference between the two is the length the muscle is moved as well as the joint. When it comes to patients with arthritis, we may use a series of static exercises.

As you may have guessed, static data refers to a fixed data set—or, data that remains the same after it's collected. Dynamic data, on the other hand, continually changes after it's recorded in order to maintain its integrity. In concept, the difference between static and dynamic data is simple enough to understand.

Both monitor the health and condition of a rotating asset like a pump, fan, compressor, mixer, agitator, or conveyor. But condition monitoring focuses on real-time conditions, while predictive maintenance has focused on the very early detection of defects 60 or 90 days in advance.

b) Dynamic load. Static loads or forces are loads that do not change in size, position or direction. On the other hand, dynamic loads or forces are loads that have change in either size, position or direction.

One of the key difference between a static and a non-static method is that static method belongs to a class while non-static method belongs to the instance. This means you can call a static method without creating any instance of the class by just using the name of the class e.g. Math.

In centreless grinding, the workpiece is rotated by the friction between the regulating wheel and the workpiece. In cylindrical grinding, the workpiece is rotated by the headstock.

What is the major difference between static electricity and current electricity? Current electricity involves a flow of electrons and static electricity involves a single transfer of electrons.
