This site may help. Plug in all the information about your load requirements and it will figure out wire and breaker size and even how big a conduit you'd need for the run.

Volume of triangular pyramid


Here is to get you started. To increase the size of the image do a CTRL Plus (+) in your browser.
You need to calculate the slant height of the pyramid for the formula of the lateral area. You should find a value of (1/2)*SQRT(203) or about 7.1239 cm

You need to calculate the altitude (height) of the pyramid from the apex (summit) to the center of the base triangle (center of inscribed circle, barycenter, orthocenter). The hypotenuse of such triangle is the slant height. One leg is the altitude (to be found), the measure of the second leg is (1/3) the altitude of the equilateral triangle that forms the base. You should find (1/3) m MH= (1/3)* (11/2)*SQRT(3)
bc7a3bcd-ec6e-4936-9887-c6372904fe9f.png

1. Calculate the area of the base (use a formula for the equilateral triangle or the general formula for a triangle: you have its height MH ).
2. Lateral area = 3 times the area of triangle Triangle ECD (in yellow above).
3. Total area = area of base + lateral area.
4. Volume= (1/3)(Area of base)* (height of pyramid)
If you can see the details on the screen capture below, fine, Press CTRL + in your browser to increase the size.

How can we calculate the stranded wire to ampere? what is the formula?


Cooking ranges are generally only a 30 AMP circuit, therefore you would need number 10 gauge Wire. If the range is a 50 Amp cook top then you will need Number 8 gauge wire.
The formula to use is Watt / Volts = amps.
Below is a wire sizing chart to help.
This chart refers to copper wire and not Aluminum.

I need to produce a diagram of a typical wiring system for a small factory showing the arrangment from the incomeing service cable to a 3-phase motor, with seperate distribution to lighting and other...


Are you asking how to draw it like CAD or what to include in the diagram. I would hate to ask why you have to produce this diagram. This type of diagram is always furnished with the complete electrical drawings of a facility when built. To produce an ACCURATE diagram is not so simple. Normally you would also include the wires sizes, conduit sizes, and panels and sub panels as well as main trainsformer size. If this diagram is to be used to say calculate available fault currents for an arc flash study, it should only be done by an experienced individual, such as an electrical engineer. Are you getting paid enough for this responsibility?

For an 3 Tn unit- single phase- 220 V a.c and gfor


There should be a full load amps or rated load amps on each of these units on the rating or nameplate. The ampacity or fuse size and wire size, which I think that's what you are wanting to know . The fuse size would be full or rated load amps times 125% and the wire size depending on the length of the run, 50 feet or less, (15 amps 14 gauge wire), (20 amps 12 gauge), (30 amps 10 gauge), and (40 amps 8 gauge).

What size duct do I need


there are online formula to calculate what you want
google ---formula to calculate air flow in pipes--
calculation will have to allow for the turbulence and restriction caused by the spiral construction of the tubing and the bends involved so you may have to incorporate several formulas to get the desired result
distance is critical as there are frictional coefficients to be considered as well
I would consider from large shop air circulation systems (as you see in Aldi, woolworths , sears etc ) that a staged diameter difference from motor to exhaust point be considered as that will keep a steady air flow for the length of the tube and a hp rating of 3hp 3 phase as a minimum
Talk with the engineers of shop and factory air conditioner designers and installers to get a close idea to what would be suitable for you

Heat load calculation


Here are a few ways to calculate your BTU's.
Get ready to use that algebra you thought you'd never use.
1 Ton = 12000 BTU's
400cubic feet per minute (CFM) = 1 Ton on standard ac units (300 is an absolute minnimum)
BTU's air heat = difference in temp. ( ∆T ) x 1.08 x CFM
∆T = BTU's / (1.08 x CFM)
i.e. 65F entering your unit and 93F air leaving on a 12000BTU unit.
∆T = 28
CFM = 400
28 x 1.08 x 400 = 12096BTU's
Another way...
Electric heat calculations.
BTU's = KW (killowatts) x 3413
Watts = Volts x Amps (single Phase) Most Homes))
Watts = Volts x Amps x Phase (this is for three phase units.)three wires and a ground))
120 volts 30 amps single phase (common)
120 x 30.0 x 1 = 3600 or 3.6KW 3.6 x 3413 = 12286BTU's
