In that case, equation (3) is sufficient to calculate the absorption process. 2.2 Equilibrium models The concentration of CO2 in the gas may be ex-...2. Yang-Mills Theory Pure electromagnetism is a free theory of a massless spin 1 ﬁeld. We can ask: is it possible to construct an interacting theory of spin 1 ﬁelds? The answer is yes, and the resulting theory is known as Yang-Mills. The purpose of this section is to introduce this theory and some of its properties.

A survey of wet cooling tower literature was performed to develop a simplified method of cooling tower design and simulation for use in power plant cycle optimization. The theory of heat exchange in wet cooling towers is briefly summarized. The Merkel equation (the fundamental equation of heat transfer in wet cooling towers) is presented and ...on outlet conditions of cooling tower— Tw,o and hs,w,o, it cannot be computed directly. Consequently, the outlet conditions of cooling tower need to be guessed initially at the reasonable values, and iterative computation is engaged for Equation (1)-(9) to calculate the ultimate results.
