Experience in using a user-friendly
software, Mathcad, in the sophomore material and energy balance
course is discussed. Example problems considered for illustration
deal with solution of linear algebraic equations (parameter
estimation, mass balances) and nonlinear algebraic equations
(equilibrium calculations for multiple reactions, vapor-liquid
equilibrium calculations for mixtures, solutions of equations of
state). The capabilities of Mathcad are of significant benefit in
accelerating the learning and
strengthening the fundamental knowledge base.
