Large Scale Rotating Rig ( Lsrr )

The first time using a large windmill to use electricity was in Cleveland, Ohio in 1888 invented by Charles F. Brush. The Brush machine was a post mill with a multiple blade picket fence rotor 17 meters in diameter, featuring a large tail hinged to turn the rotor out of the wind. It was the first windmill to incorporate a step up gearbox in order to turn a direct current generator at its required operational speed. In 1891, the Dane Poul La Cour developed the first electrical output wind machine to incorporate the aerodynamic design principles used in the best European tower mills. By

Specific Purpose: To inform the audience about the history of the four-stroke engine, how it works and some brief information to other types of engines.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

4. Remelt the contents of the tube and add the counterpart component based on the given schedule. Ask the demonstrator to adjust the cooling water between mixtures. During the experiment, record and plot the data obtained for all mixtures listed. The experiments are stopped as follows:

Turbine: A machine that converts the energy from a moving fluid into rotary motion, and is used to produce continuous power.

Dabiri of California Institute of Technology associated with aquatic bio forms. Wind turbines are the Colossus of the modern landscape and the blades can sweep up to a football field in diameter. Critics call this particular invention unsightly while the blades clobber unsuspecting birds. There is also an a efficiency problem while the blades become more powerful, but they’re size requires that they be spaced apart, this means they take up a lot of land. John Dabiri of Caltech also found a solution underwater and also built an experimental wind farm-(FLOWE). In which the location of turbine relative to each other takes advantage of air flow among them” Dabiri 1. “The turbine placement was determined by studying the wake vortices produced by schools of swimming fish” Dabiri 1. Dabiri’s 30 ft. tall wind turbine has blades that gather energy generated as wind flows through the wind farm. The blades take advantage of the wind’s behavior, for energy production, the way fish take advantage of water’s behavior for forward

This dilemma made designing the propeller one of the Wright brothers most challenging problems. Despite the lack of previous information to consult, the brothers were able to learn, through investigation and trial/error, that large propeller diameters would produce high thrust for a given power input. The brothers also determined that high torque produced by large, slow turning blades adversely affected the flying qualities (p-factor). On their first aircraft, they utilized 8 ½ ft propellers installed behind the wind to minimize airflow disturbance, incorporated counter-rotating propellers to eliminate the problems associated with torque, and gained thrust efficiency by reducing the blades’ rotational speed using a chain and sprocket transmission. The Wright brother’s propeller was 66% efficient which was much higher that any other propeller of the time. The foundations of a disciplined approach to propeller design evolved soon thereafter. With the advancements and refinements made by early inventors, engineers could use those test results to design propellers with better performance and structural reliability. These advancements led to the development of the first generation of well-designed propellers. One of the first designs was the “Integrale”, developed by Lucien Chauviere, the world’s first industry standard propeller manufacturer. By 1910, the number of propeller producers multiplied, and numerous

This project investigates the current available designs of wind turbine and examines the predicted future advancements of the same. The project also allows us to perform certain tests not only verifying the efficiency of the various wind turbine designs but also the efficiency of a ‘pulley belt type dynamometer’. This report explains the very basics involved in the study of Wind Turbo machinery. The report commences with a very brief introduction of the project aim and of all the other elements

6. The outflow rate is measured by using a measuring cylinder. It is measured 3 times and averaged for a more accurate result. The results are shown in Table 2.

The aim of this experiment is to build and understand the basics of the operation of a hot water tank sequence.

The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT, where R represents the gas law constant. To determine R, we must find the other parameters, P, V, n and T through the experiment.

Designing a gas pipeline requires four aspects, the first aspect determines the length and direction of pipeline, the second aspect determines the size of pipes and compressors, the third aspect is to determine pressure and gas flow distribution in the pipeline transmission system .The fourth aspects considers the chance of demands for growing of gas over time so the capacity of the system may be needed to be increased by adding other components in parallel or series. (O. A. Almisned, 2002 ) Moreover, in this research a gas pipeline is designed taking into account the fluid type, transportation distances, diameter, wall thickness, material selection and other properties to determine the criteria for the pipeline. A computer programming Pipesim simulator is a steady-state, multiphase flow for designing and badge investigation of gas production systems. in addition to, the programmer investigates flow line and performance of surface facility to produce full production system analysis.

Jan De Nul jack-up Vole au Vent lifted the seventh of 10 Siemens 4.2 MW turbines into place during a reNEWS visit to Finland's first commercial wind farm last Thursday.

For all of the tests conducted, the same apparatus was used, and the sample materials in the system were not altered between any of the tests. Seeing as the same apparatus was used for all tests, the inner chamber diameter of 2 inches remained constant for all tests. Additionally, the apparatus was purged with nitrogen immediately before the start of each trial to ensure that diffusion did not begin before the start of the timer. The information that was recorded for each test included the elapsed time, the weight of the condenser both before and after collecting the vapors, and the distance from the point of collection to the gas-liquid interface. In addition, the room temperature and pressure was recorded each day due to the role of these measurements in calculating the predicted values.

Measured properties in the system include the wet and dry bulb temperatures at the inlet and outlet, the temperature of the water in and out, the make-up temperature and the pressure. The power to the heat is predetermined as well as the water mass flow rate. The enthalpy, absolute humidity and the specific
