The propeller is coupled to the turbine through a reduction gear that converts the high RPM‚ low torque output to low RPM‚ high torque. The propeller itself is normally a constant speed (variable pitch) type similar to that used with larger reciprocating aircraft engines. Turboprop engines are generally used on small subsonic aircraft‚ but some aircraft outfitted with turboprops have cruising speeds in excess of 500 kt (926 km/h‚ 575 mph). Large military and civil aircraft‚ such as the Lockheed

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes

3.1 Principle of Refrigeration[16]: Mechanical refrigeration is done by three processes that are circulation‚ evaporation‚ and condensing a fixed supply of refrigerant in a closed system. Evaporation takes place at a low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus‚ it is possible to transfer heat from an area of low temperature (i.e.‚ water storage tank) to an area of high temperature (i.e.‚ environment). Regarding to the fig 3.1‚ beginning

backlash in the scotch yoke. It is now mainly used in computing type applications where harmonic motion is required. The Scotch yoke is a mechanism for converting the linear motion of a slider into rotational motion or vice-versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part. The shape of the motion of the piston is a pure sine wave over time given a constant rotational speed. This setup is most commonly used in control valve actuators in

moment on the crank shaft and crank angle for a given force on the piston. Equipment and Instrument: Introduction: A crank is an arm attached at right angles to a rotating shaft by which reciprocating motion is imparted to or received from the shaft. It is used to convert circular motion into reciprocating motion‚ or vice-versa. The arm may be a bent portion of the shaft‚ or a separate arm attached to it. Attached to the end of the crank by a pivot is a rod‚ usually called a connecting rod. The

A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails.[1][2] Originally‚ windmills were developed for milling grain for food production. In the course of history‚ the windmill machinery was adapted to many other industrial uses.[3] An important non-milling use is to pump water‚ either for land drainage or to extract groundwater.
