In two dimensions, we have five flow properties that are unknowns: the two velocity components u,v; density r, temperature T and pressure p. Therefore, we need 5 equations linking them. One of these 5 equations is the equation of state, given by

Binary Adders: Half Adders and Full Adders

Each type of adder functions to add two binary bits. In order to understand the functioning of either of these circuits, we must speak of arithmetic in terms that I learned in the second grade.
