For a metal containing only one type of charge carrier (electrons), the Hall voltage (V H) can be calculated as a factor of current (I), magnetic field (B), thickness of the conductor plate (t), and charge carrier density (n) of the carrier electrons: VH = − IB net. In this formula, e represents the elementary charge.Laminar flow is characterized by the gliding of concentric cylindrical layers past one another in orderly fashion. The velocity of the fluid is at its maximum at the pipe axis and decreases sharply to zero at the wall. The pressure drop caused by friction of laminar flow does not depend of the roughness of pipe.The formula for calculating molar concentration, known as molarity, is the total moles of the solute divided by the total amount of the solution in liters. Molarity is sometimes indicated by an M, which means moles per liter.

A radius is half of a circle’s diameter. Imagine a circle drawn so its curved surface conforms to the bend shape. As the bend angle gets wider, the circle needs to get larger to conform to the bend shape; a larger circle, of course, has a larger radius. This is how we measure the inside bend radius in precision sheet metal fabrication.

1-1/4. The code requires a minimum radius for rigid conduit bends because when bends are too tight, wire pulling becomes more difficult and the insulation on the conductors may be damaged .

You are making a concentric bend and the radius of the first pipe is 16 inches, the OD of the first pipe is 2 inches, and the spacing between pipes is 3 inches. What is the radius of the second pipe?Circular tube is a symmetric section though, for any possible axis through the center. As a result, the plastic neutral axis, should pass through the center too, when only a bending moment is applied. In the general case, the plastic section modulus is given by the following formula (assuming bending around x axis):Measure from the end of the conduit to the wall – perhaps it's 25 ½".
