d_b = 0.5*d/sqrt(n)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Diameter of Bolt - (Measured in Millimeter) - Diameter of Bolt is the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
Shaft Diameter - (Measured in Millimeter) - Shaft Diameter refers to the measurement of the width or thickness of a cylindrical or rod-like component known as a shaft.
Number of Bolts - Number of Bolts is simply defined as the number of bolts that are under our consideration.

STEP 1: Convert Input(s) to Base Unit

Shaft Diameter: 1200 Millimeter --> 1200 Millimeter No Conversion Required
Number of Bolts: 3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_b = 0.5*d/sqrt(n) --> 0.5*1200/sqrt(3)

Evaluating ... ...

d_b = 346.410161513776

STEP 3: Convert Result to Output's Unit

0.346410161513776 Meter -->346.410161513776 Millimeter (Check conversion here)

What is Flange Coupling?

A flange coupling is a type of mechanical connection used to join two rotating shafts in machinery and equipment. It consists of two flanges, typically circular discs with a series of bolt holes around their perimeter. These flanges are attached to the ends of the shafts to be connected.The flanges are aligned so that their bolt holes match up, and bolts are inserted and tightened through the holes to securely join the two shafts together. This creates a rigid and strong connection between the shafts, allowing for the efficient transmission of power and torque from one shaft to the other.

What is an Agitator ?

An agitator is a device or mechanism used in various industrial and manufacturing processes to mix, stir, or shake substances within a container or vessel. It is designed to promote the blending of different components, facilitate chemical reactions, prevent settling or separation of solids in liquids, and ensure uniform distribution of substances within a mixture. Agitators are commonly used in industries such as chemical processing, pharmaceuticals, food and beverage, wastewater treatment, and many others.
