Arc Length of a Curve: Problem Solving

Arc Length of a Curve: Problem Solving

A high-voltage power line spans a 40-meter horizontal distance between two transmission towers, resulting in a 10-meter vertical sag due to the effects of gravity and thermal expansion. The curve formed by the suspended cable is a catenary, which accurately models the behavior of a uniform, flexible cable under its own weight. Unlike a parabolic shape, the catenary is described by the hyperbolic cosine function and offers a precise representation of the cable's form.In this setup, engineers...

Residual Stresses

Residual Stresses

Residual stresses reside in a structure even after removing the original stress inducer. This phenomenon often arises from varied plastic deformations across different parts of a structure. Consider a rod stretched beyond its yield point. It will not regain its original length due to permanent deformation. Even after load removal, the rod does not entirely lose stress because of uneven plastic deformations, resulting in residual stresses. The computation of these stresses in structures is...

Underflow Gates

Underflow Gates

Underflow gates are vital for controlling water flow in irrigation canals. The three main types of underflow gates — vertical, radial, and drum gates — serve different purposes while ensuring effective flow management. Vertical gates move up and down, generating a free-flowing water jet; radial gates pivot to regulate the flow; and drum gates rotate for precise adjustments. The flow through these gates is influenced by downstream conditions, resulting in free or drowned outflow.Free and...

Area of Science:

Environmental Science
Chemical Engineering
Plasma Physics

Background:

Produced water, wastewater from shale hydraulic fracturing, has high electric conductivity (50-200 mS/cm).
This conductivity presents challenges and opportunities for plasma-based treatment methods.

Purpose of the Study:

To investigate the feasibility of stretching an arc discharge in produced water.
To enhance the volume of produced water treated by plasma.

Main Methods:

An arc discharge was stretched using a ground electrode and two high-voltage electrodes.
One high-voltage electrode was placed close to the ground electrode, while the other was positioned farther away.

Main Results:

Stretching the arc significantly increased the contact area between the arc and produced water.
This increased contact led to more efficient plasma treatment.

Conclusions:

Stretching arc discharges is a feasible method for improving plasma treatment of produced water.
The technique offers enhanced performance and energy cost-effectiveness for wastewater treatment.
