The easiest way is to find the centerline length and multiply that by the linear weight of the pipe size being used.

Alternatively, this formula should give the weight of an elbow in pounds:

w=0.071*pi^2*R*(ro^2-ri^2)

Where:

w= weight of elbow (lb)

R=curve radius of elbow (in)

ro=outside radius of pipe (in)

ri=inside radius of pipe (in)

There is no specific standard for PLC inputs or outputs, as existing standards wire color codes are based on voltage rather than by function.

Different standards apply in the USA, Europe or other countries, and it depends if you intend to wire a PLC for a domestic application or it is going to another place where the requirements may be different to the local ones. Check it.

These standards my help you:

NFPA 79

UL 508A

IEC 204.1 / EN 60204-1

If you mention where you are located or where is that piece of equipment going, maybe I can give you further info.

Rotary Broaching is a method of producing both internal and external forms fast and accurately on the end of a workpiece. Rotary broaching makes it possible to very accurate forms within 0.0005 inches within seconds.

With rotary broaching not only can you produce standard shapes such as hexagons and squares but also shapes such as Double Hex Rotary Broaches, 6-Lobe Rotary Broaches, Serration Rotary Broaches, J500 Rotary Broaches, Spline Rotary Broaches, Involute Rotary Broaches, Torx Rotary Broaches, Double D Rotary Broaches and any other Special Design Required. Rotary broaches can be made to just about any size, English or Metric.

Some of the material that can be rotary broached is brass, aluminum and steel and can go as much as 2 inches deep.

In relation to a/c mains electricity, or to audio frequencies, 400 kHz is very high. In relation to radio waves it is fairly low.

They are made in a large variety of types. Some of these are shown in the linked article.

A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load.

The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage.

The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.

In resin impregnation, any porous material is made impervious by filling its pores with the resin.

Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator

An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.

Short bead as well as arc strikes create a sudden localized temperature increase to the metal and can cause cracking.

Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection.

Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.

American society of mechanical engineers has a classification of pressure vessels. Certain type of the boilers have H stamp according their classification, and this stamp is required by local authorities in order to get boiler approved for installation.

To calculate the admittance if you are given the impedance, you take the inverse of the impedance ( that is 1/z).

Cable schedules provided a tabulated list of all cables with relevant details such as cable number, cable type, size and rating, voltage, number of cores and length of route. Cable schedules are applicable for power cables, control cables, instrumentation cables and industrial data communication cables. In addition to the cable schedules, termination diagrams are provided for use by the electrical installation contractor.

Chiltons manual says 170 horsepower and 275 ft.-lbs. of torque.

A good example of Bending Force would be a beam or a pillar. Also a rubber band or elastic.

I hope this helped,

jigging is the name of the process of hanging items on a wire prior to suspending into molten zinc to galvanize the steel

Calibration is required to maintain the accuracy and reliability of instruments.

The density of steel as per IS 2062 will vary. This is because steel's density typically changes with composition.
