6.6.2 Poly(ethylene Terephthalate)1-2 6.6.2.1 General Poly(ethylene terephthalate)‚ or PET‚ is a thermoplastic polyester resin. Such resins may be classified as low-viscosity or high-viscosity resins. Low-viscosity PET typically has an intrinsic viscosity of less than 0.75‚ while high-viscosity PET typically has an intrinsic viscosity of 0.9 or higher. Low-viscosity resins‚ which are sometimes referred to as "staple" PET (when used in textile applications)‚ are used in a wide variety of products

2008 AACE INTERNATIONAL TRANSACTIONS EST.03 An Introduction to Parametric Estimating Mr. Larry R. Dysert‚ CCC A ACE International describes cost estimating as the “predictive process used to quantify‚ cost‚ and price the resources required by the scope of an asset investment option‚ activity‚ or project [1].” The methods and techniques used to prepare a cost estimate will typically vary based on the level of project definition available at the time the estimate is prepared [2‚ 3]. Early in a project’s

the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2-4 liters per hour or 10-14 liters per day‚ but is less in children prior to puberty. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. Hence‚ in hot weather‚ or when the individual’s muscles heat up due to exertion‚ more sweat is produced. Animals with few sweat glands‚ such as dogs‚ accomplish similar temperature regulation results by panting‚ which evaporates

four basic components must be present for the cooling process to take place. There are a few components in heat pumps that do not show up in air conditioners. These devices are what make the air conditioner into a heat pump. The reversing valve reverses the refrigerant flow in an air conditioner to enable it to produce heat in the space where cooling is usually produced. A second metering device is present in the outdoor unit to enable the cooling effect to take place in the outdoor coil. The

What is the effect of a non-volatile impurity on the boiling point of a substance? of a volatile impurity? A non volatile impurity which is added to the volatile liquid‚ it’s boiling point will increase. It is due to some of effective surface area which is available for evoperation is occupied by non volatile substance. If another volatile impurity is added then 1) if it does not chemically react with given liquid then boiling point will decreade due to increase in vapour pressure. 2) if it chemically

Begin with an efficient water cooled variable speed chiller‚ add high efficiency air handlers‚ low-pressure drop components‚ and finish with an integrated control system that minimizes unnecessary dehumidification and simultaneous heating and cooling. • Benchmark existing facilities Use temperature resets to allow use of

There are two pieces of literature used as the focal point of this review‚ they are; Tracey Booth’s journal article from the Australian & New Zealand Journal of Criminology entitled ‘Cooling out’ (2012)‚ and the third chapter from James Dignam’s published University text entitled ‘Victims and the Criminal Justice System’. The focus of Booths articles is on managing the victim’s participation in the sentencing process in order to reduce

Vapour cycle cooling system (VCCS) is more easier to used on small aircraft because its required a minimum power for a given of cooling and also allow the aircraft to be cooled on the ground as well. The basic function of vapour cycle cooling system(VCCS) is to give accurate cooling at aircraft cabin and also
