A transformer’s rated temperature rise (degrees Celsius) is the average temperature of the transformer’s windings over an ambient temperature of 40°C. In other words, the average winding temperature = ambient temperature rise.

A transformer is a tool that takes the output of a Dapp and converts it to another format. Current transformers include: RSS, email, HTML, Google Maps, and more. To transform a Dapp, find or create a Dapp and then click the 'more uses' button to see the available set of transformers. See similar questions...

Acoustic foams, which are thermally insulating - may act to insulate components so that heat is not so easily transmitted to the case sides and top and bottom for dissipation to the outside. This may cause slight increases in temperature. The configuration of the materials around the case interior and components may also be such that airflow pathways become more tortuous. This is only likely where materials have been fitted incorrectly so that they obstruct airflow - which is NOT recommended. See similar questions...

Touch is a poor indicator of proper transformer operating temperature. Properly designed transformers can reach 50°C (122°F) above ambient temperature. In an ambient temperature of 20°C (60°F), the total temperature can reach 70°C (190°F), which is too hot to touch. Thermometers are the best way to determine the temperature.

A fire door that by code, meets a maximum unexposed surface temperature requirement at a specified time interval during the fire test. (i.e. 250 deg @ 30 minutes) See similar questions...

Answer: Temperature rise doors are used in stairwells. In the case of fire on one side of the door, the unexposed side of the door must remain below 450 degrees F for 30 minutes. This type of door is required on all fire rated stairwell doors (SBC 705.1.3.4). The reason for this requirement is to protect escaping occupants. A standard metal door exposed to fire can reach 1200 degrees F on the unexposed side, and this amount of heat could cause clothes on an exiting occupant to catch on fire. See similar questions...

The Kelvin (K) is the unit of color temperature. 4100K is the brightest, most natural white light similar to that of daytime sunlight, and therefore the HID color temperature used most in the OEM automotive industry. When you look at the light coming directly out of an HID headlight, it possesses a bit of a blue or purple hue which most people recognize as the expensive, elegant look characteristic of HID's. For this reason, some HID kit manufacturers produce 5400K, 6500K, 8000K, etc. See similar questions...

Yes. Transformers are tools which transform the raw XML produced by Dapper to various useful formats. Soon, we will release the code of the existing transformers and an API that will allow you to build new transformers and add them to the current existing list. See similar questions...

Answer: It is the industry's highest rating for this type of space heating equipment and allows us to deliver the maximum amount of heat with the minimum amount of outside air. The maximum 160°F temperature rise/discharge temperature rating is crucial because it translates into lower horsepower motors, less outside air and reduced energy costs. See similar questions...

The long-term service temperature is defined as being the maximum temperature at which plastics can be kept in hot air for 10,000 and 20,000 hours without losing more than 50% of the initial values for their typical properties. The short-term service temperatures are the short-term peak temperature values that the plastic can withstand for a period of minutes or sometimes even hours without the plastic being damaged, taking into account the load and its duration.

increasing number of cases of pertussis have been reported to the CDC since the 1980s. The increases are greatest among adolescents (aged 10-19 years), but an increase is also seen among infants younger than 5 months old. The reported increases may reflect greater awareness of pertussis to some degree. Even with the increase in reports among adolescents and very young infants, the number of reported cases is more than 97 % lower than in the pre-vaccine era. See similar questions...

During warm periods when temperatures rise above freezing, pressure develops in the tree. This pressure causes the sap to flow out of the tree through a wound or tap hole. During cooler periods when temperatures fall below freezing, suction develops, drawing water into the tree. This replenishes the sap in the tree, allowing it to flow again during the next warm period. Sap flows through a portion of the outer tree trunk called sapwood. See similar questions...

The fee increased (as planned) $2/quarter in 2006-07 (to $50), and again in 2007-08 to $52. At this point we hope to have reached cost recovery for both the infrastructure costs and ResComp costs. Future increases, though difficult to predict exactly, should be only incremental. See similar questions...

The Omron Instant Ear Thermometer is less threatening to a child than a rectal thermometer. It's faster, safer and easier to use than an oral thermometer. Measurements can even be taken while a child is sleeping. For adults, the Omron Instant Ear Thermometer offers fast convenient, accurate readings without the wait of a conventional thermometer. A fever is when the body's temperature is higher than normal due to an infection. The fever is usually caused by a virus or bacteria. See similar questions...
