English units calculation form

The American Society of Agricultural Engineers (ASAE) http //www.asae.org. Psychrometric data in chart and equation form in both SI and English units. Charts for temperature ranges of -35 to 600°F in uses units and -10 to 120°C in SI units. Equations and calculation procedures. Air-water system and Grosvenor (temperature-humidity) charts only. 

Obtain information on alternative units of measure used to express values of energy as heat and other forms of energy. Also, find out how the quantities relate to SI units. Include information specifically on English units, such as the British thermal unit (BTU), and on typical BTU ratings of household appliances. Calculate how these ratings would be expressed in joules instead. 

A program for hydraulic calculations, hydraulics.exe, has been developed to estimate pressure drop for noncompressible fluids, compressible fluids, and two-phase fluids. The main form has been divided into a number of frames for input and results. Calculations can be performed using either SI or English units (SI unit by default). The units are fixed ones, and the program does not allow for change of individual units. 

A program to estimate the height of flare stack, Flarestack.exe, has been developed for simple and Brzustowski and Sommer approaches. One sketch has been added to the main form to understand the dimensions and parameters. The calculation can be performed by using either SI or English units... 

For example, a clearly defined working concept of an element was essential for the elaboration of the atomic theory by John Dalton (1766-1844). In 1808, this English schoolmaster published A New System of Chemical Philosophy in which he put forth his postulates about the structure of matter. Each element, Dalton argued, is constituted of identical, immutable, and uniquely characteristic atoms. When elements combine to form compounds, then-atoms unite in a fixed ratio that is characteristic of the compound. Because these numbers are fixed, the elementary composition of the compound, by mass, is also constant. This latter property could be quite accurately determined, even in Dalton s time. However, Dalton had no direct way of ascertaining the correct atomic ratio of the elements of any compound. As a consequence, he could not calculate, with confidence, the relative masses of the atoms of the various elements—their atomic masses or atomic weights. The atomic masses of the elements and the atomic ratios characteristic of specific compounds are manifested in the elementary mass composition of the compounds. Once the correct atomic ratio is known, atomic masses can be readily calculated from mass composition. Alternatively, knowledge of atomic masses permits conversion of composition by mass to composition by atomic ratio. However, Dalton faced the dilemma of an equation with two unknowns.
