VB 3.0 Heat and Mass Balance for Deaerator

This program developed using Visual Basic 3.0 for calculate the deaerator of small scale CFSPP's heat and mass balance. The variable inputs are:

  1. Pressure [bar]
  2. Temperature [C]
  3. Deaerator efficiency [%]
Calculation results are:

  1. Steam Flow required from high pressure pipe (from turbine)[kg/s]
  2. Water Flow required from LP Heater [kg/s]

and also calculate The Steam and water properties:

  1. Enthalpy [kj/kg]
  2. Steam_flow [kg/s]
  3. Specific Volume [m3/kg]
  4. Specific Entropy [kJ/kg.K]
  5. Internal energy [kJ/kg]
  6. Dynamic Viscosity [kg/m.s]
  7. Thermal Conduct [W/m.K]
