Mole Balance Energy Balance
Specifications 2 equations 2 unknowns
Specify V, find T and X
Specify X,find T and V
Specify T, find X and V
- Excel solver or POLYMATH nonlinear equation
solver - B. Graphical Solution of X vs T
- C. Graphical solution of Qremoved, Qgenerated
vs. T
Determine T Liquids 1) Calculate T from energy
balance 2) Calculate k given T Gases 1)
Estimate T by assuming ?Hrxn and Cp are
constant 2) Use Excel solver or Polymath
nonlinear Equations solver (NLE) to solve for T.
Determine V from mole balance
Calculate X (EB) Calculate V
