They sold us a lemon. The car broke 4 months after we bought it. Had to replace the transfer case ($4,000). The roof leaked when it rained ($500). Not to mention when we first got the car, all the...
When performing temperature tests, it is important to. use a good, accurate thermometer that is surrounded. by at least three inches of concrete. Take readings. quickly, noting that small samples lose heat fast. Concrete temperatures are affected by the mix-water. temperature, aggregate temperatures, cement type. and admixture type. Optimum concrete temperatures. will aid with setting, early strength development, proper curing and ultimately aid in achieving a higher. quality concrete. Hot concrete sets up rapidly, gaining.
If the ambient temperature (DBT) is 120F and relative humidity is 50 %, how much an evaporative cooling will drop the temperature, ie WBT=? Around 30 degrees or to 90F could be possible with an evaporative cooler. The lower the humidity the better an evaporative cooler will work.
