Wilbur Scoville Wilbur Scoville Wilbur Lincoln Scoville (January 22, 1865 – March 10, 1942) was an American pharmacist best known for his creation of the "Scoville Organoleptic Test", now standardized as the Scoville scale. He devised the test and scale in 1912 while working at the Parke-Davis pharmaceutical company to measure pungency, "spiciness" or "heat", of various chili peppers. Scoville was born in Bridgeport, Connecticut. He married Cora B. Upham on September 1, 1891 in Wollaston (Quincy, Massachusetts). They had two children: Amy Augusta, born August 21, 1892 and Ruth Upham, born October 21, 1897. Scoville wrote "The Art of Compounding", which
Heat exchanger temperatures. We find the total energy transferred by integrating the expressions for the time rate of change of internal energy per unit length: By the conservation of energy, the sum of the two energies is zero. The quantity formula_30 is known as the "Log mean temperature difference", and is a measure of the effectiveness of the heat exchanger in transferring heat energy. Heat exchanger A heat exchanger is a device used to transfer heat between two or more fluids. In other words, heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid
