Punjabi: A Cognitive-Descriptive Grammar
ISBN: 9780415003209 / Angielski / Twarda / 1993 / 460 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) This is a complete grammatical description of Panjabi, an Indo-European language spoken in India and Pakistan, as well as in other countries outside Asia (particularly in the United Kingdom and Canada) by approximately 45 million people, either as a first or a second language. It is recognized as one of the 15 official languages of India. Primarily written in three distinct scripts (Gurumukhi, Perso-Arabic, and Devanagari), a unique feature of the language is that it is tonal in nature. Along with Lahanda and the Western Pahari (Himalayan) dialects, Panjabi is the only modern Indo-European...

Electrical Conductors: Quick Book
ISBN: 9781508498216 / Angielski / Miękka / 2015 / 30 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Wires are very good conductors, which mean that they have very little resistance. In fact, their resistance is so small that often we consider it to be zero. (In other words, we often treat wires as perfect conductors). In United States, conductors are measured by American wire gauge (abbreviated AWG) for smaller ones, and circular mils for larger ones. To give you some idea how thick these wires are; AWG 0000 wire is about 11.7 millimeters in diameter (a little less than one-half inch...

Overview of Refractories: Quick Book
ISBN: 9781505407327 / Angielski / Miękka / 2014 / 68 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) Refractories are inorganic, nonmetallic heat resistant materials that can withstand extreme temperatures, and in many cases chemical attack, abrasion, thermal shock and rough handling. These are widely used in the lining of high temperature surfaces viz. furnaces, kilns, reactors and other processing units in manufacturing, thermal, metallurgical and chemical equipments worldwide. Refractory selection for a specific application is invariably built upon a combination of material qualities and its composition. Refractories are expensive, and any failure in the refractories can result in a great...

Overview of Electric Overhead Traveling (EOT) Cranes: e-Book
ISBN: 9781502515933 / Angielski / Miękka / 2014 / 202 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) An overhead crane, also known as a bridge crane, is a type of crane where the hook and line mechanism runs along a horizontal beam that itself travels on the two widely separated rails. Often it is in a factory building and runs along rails mounted on the two long walls. A gantry crane is similar to an overhead crane, but here the bridge carrying the trolley is rigidly supported on two or more legs moving on fixed rails embedded in the floor. Overhead traveling cranes are also available in various configurations. The two main categorizations are top-running versus under-running bridge cranes...

Natural Ventilation Principles and Practices: HVAC e-Book
ISBN: 9781502771902 / Angielski / Miękka / 2014 / 86 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) Natural ventilation refers to the process of exchanging warm building air for cooler outside air without the use of energy-consuming mechanical devices, such as fans and air conditioners. With an increased awareness of the cost and environmental impacts of energy use, natural ventilation has become an increasingly attractive method for providing acceptable indoor environmental quality and maintaining a healthy, comfortable, productive indoor climate. In favorable climates, natural ventilation can be used as an alternative to air-conditioning systems, saving 10%-30% of total energy...

20 Ways to Optimize Efficiency in the Use of Induction Motors: Quick Book
ISBN: 9781508586296 / Angielski / Miękka / 2015 / 86 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) The majority of electrical energy consumed in most industrial facilities is used to run electric motors. Annual energy operating costs of electric motors usually far exceed purchase prices. For example, a typical 25 horsepower (hp) motor running at full load for 6,000 hours per year would consume nearly $10,000 of electricity annually. An average purchase price for a motor of this size would be only $500 to $600. Energy efficiency decisions are important decisions that affect operating cost for the life of the equipment. By optimizing the efficiency of your motor-driven systems, you can...

HVAC Heating Load Calculations and Principles: Quick Book
ISBN: 9781503361829 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) The prime requirement in respect of the indoor climate in a building is that room temperature should be at a comfortable level, regardless of the weather conditions outside. As soon as the ambient temperature is lower than the indoor temperature, heat flows out from the building through its boundary surfaces (the building envelope). At the same time, the building also loses heat through air infiltration, i.e. the inward leakage of outdoor air into the building through gaps and cavities in walls, roofs, doors and windows. Bearing in mind the fact that the indoor temperature in most buildings...

Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) The HVAC systems are designed for peak conditions. Because these conditions prevail only for small period in a year, the HVAC equipment must operate most of the time at lean capacity. The function of the control system is to adjust the equipment capacity to match the load. Automatic controls are necessary not only to achieve the design conditions in the conditioned space but are also required for efficient operation of the HVAC system. The main parameters to be controlled in air conditioning system are temperature, pressure, humidity, air quality and thermal energy distribution. This 6 -hour...

HVAC Cooling Load - Calculations & Principles: Quick Book
ISBN: 9781502851369 / Angielski / Miękka / 2014 / 64 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) Heating and cooling load calculations are carried out to estimate the required capacity of heating and cooling systems, which can maintain the required conditions in the conditioned space. To estimate the required cooling or heating capacities, one has to have information regarding the design indoor and outdoor conditions, specifications of the building, specifications of the conditioned space (such as the occupancy, activity level, various appliances and equipment used etc.) and any special requirements of the particular application. For comfort applications, the required indoor conditions...

Heat Rejection Options in HVAC Systems: Quick Book
ISBN: 9781505381672 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) One of the basic requirements of the air conditioning and refrigeration system is to reject heat to the outdoors. The refrigerant chillers come in two different forms: An air-cooled chiller uses the flow of outside air across the condenser to remove or reject heat from the chiller. Air-cooled chillers typically have the condenser mounted on the roof or somewhere outside the facility while the evaporator can either be inside or outside the facility. Water-cooled chillers are typically 100 tons or greater and use water to remove the heat from the condenser. Water-cooled chillers are typically...

Principles and Methods of Temperature Measurement: Quick Book
ISBN: 9781502848635 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) Temperature is a principle parameter that needs to be monitored and controlled in most engineering applications such as heating, cooling, drying and storage. Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic be it a thermal expansion, thermoelectricity, electrical resistance or thermal radiation. There are four basic types of temperature measuring devices, each working on a different principle: 1.Mechanical (liquid-in-glass thermometers, bimetallic strips, bulb & capillary, pressure type etc.)...
