Rochowova monografija je uvod v elektrokemijo, namreč v reakcije, ki prenesejo elektrone (oksidacije, redukcije in jedrsko sevanje), in naprave, ki shranijo elektriko (baterije in akumulatorji). Čeprav jo je napisal pred petdesetimi leti, je tema dandanes še aktualnejša, saj je skrajni čas, da presedlamo s kurjenja organskih snovi (premoga, nafte) na ekološko prijaznejše vire kot so sončna, kinetična (veter, plima) in geotermalna energija. Pri teh pa potrebujemo ekonomičnejše akumulatorje. Celo jedrska energija je dandanes slabo izkoriščena: vso energijo najprej pretvorimo v toploto in jo nato speljemo skozi običajni toplotni stroj. Kakšna škoda, kajti jedrska energija je prosta energija ...
Energy Methods in Mechanics - Lecture Notes John L. Turner
Books with a 0 star rating(0)
$25.00
Size: 8.5" x 11"
Binding: Spiral Bound
This set of lecture notes and worked example problems covers topics in the application of variational and energy methods in mechanics. These are scalar based principles, as contrasted with vector approaches based on Newton’s 2nd Law. The Principle of Virtual Work is the foundation of the variational based approaches. Equilibrium and deformation equations based on virtual work and stationary potential energy are developed with applications to rods, bars, beams, frames, etc. Approximate solution methodologies derived from these techniques (e.g. Rayleigh Ritz and Finite Elements) are covered. An introduction to the use of the Calculus of Variations for continuous systems is included. ...

This flight test guide presents the essentials of safe and technically sound flight testing to the amateur-builder pilot community in a practical, easy to understand way. The flight test topics deemed important to amateur-builder flight testing derive directly from NTSB recommendations and latest FAA guidance. They represent a mixture of test philosophy and “how to do it” flight test techniques subjects with an overall emphasis on best practices and safe test conduct.
Hall Cell Technology: Estimating the Anode to Cathode Distance by Voltage Measurement H.Wayne Cotten
Books with a 0 star rating(0)
$49.95
Size: 6" x 9"
Binding: Perfect Bound
The anode to cathode distance of a Hall cell is an important parameter to understand and control. If it is excessively large energy is wasted. If it is too small current efficiency is reduced. If smaller yet, the cell will become unstable. The anode to cathode distance is adjusted by moving the anode bridge to control cell resistance. It is generally assumed in resistance calculations that the bottom of the anodes are in one plane. It is also generally assumed that the cathode surface, which is the liquid metal, is static. Thus the anode to cathode distance is generally assumed to be the distance between the two parallel planes. In this paper, a simple and accurate method will be des ...
Hall Cell Technology: Power Usage in the Hall Cell Illustrated by the Use of Two Dimensional Graphs H.Wayne Cotten
Books with a 0 star rating(0)
$49.95
Size: 6" x 9"
Binding: Perfect Bound
Power input to a cell is the product of volts and current and is therefore two dimensional. In this paper, we will use two dimensional charts to visually illustrate the power input to a cell used to make aluminum and the power used to maintain the cells heat balance. In doing so, we will also explore the power efficiency of the cell as well as defining other related efficiencies.
Hall Cell Technology: Using the Plot of Cell Voltage as a Function of Current to Determine the Current Efficiency Lost by Leakage Current Wayne Cotten

Size: 6" x 9"
Binding: Perfect Bound
In slightly more than 100 years, the electrochemical production of aluminum from aluminum oxide has grown from invention to the technology of today. The single most important change related to efficiency improvement was the application of computer control. Within computer control, the two most important programs are resistance control and alumina feed control. Within the resistance control program, the formula used to calculate a cell’s resistance utilizes a constant that is assumed to be the intercept of the resistance line at zero current. In reality, the intercept is lowered by leakage current and therefore reflects current efficiency loss due to the leakage current. The purpose o ...
