Heat duty units
WebHeat can be shifted around loops. Figure 16.24a shows the effect of shifting heat duty U around the loop. In this loop, heat duty U is simply moved from unit E to unit B. Thus loops, utility paths, and stream splits offer the degrees of freedom for manipulating the network cost. The problem is one of multivariable nonlinear optimization. WebHeat Capacity - Conversion. Heat capacity, or thermal capacity, is the measurable physical quantity of heat energy required to change the temperature of an object by a given amount. Its SI unit is joule per Kelvin. Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system.
