(a)
Interpretation:
The level response of the tank as a function of time is to be plotted if the drain is closed suddenly and the inflow is constant for 3 min.
Concept introduction:
For chemical processes, dynamic models consisting ordinary differential equations are derived through unsteady-state conservation laws. These laws generally include mass and energy balances.
The process models generally include algebraic relationships which commence from
(b)
Interpretation:
The level response of the tank as a function of time is to be plotted if the drain is opened for 15 min and the inflow is kept at
Concept introduction:
For chemical processes, dynamic models consisting ordinary differential equations are derived through unsteady-state conservation laws. These laws generally include mass and energy balances.
The process models generally include algebraic relationships which commence from thermodynamics, transport phenomena, chemical kinetics, and physical properties of the processes.
(c)
Interpretation:
The level response of the tank as a function of time is to be plotted if the inflow is doubled to
Concept introduction:
For chemical processes, dynamic models consisting ordinary differential equations are derived through unsteady-state conservation laws. These laws generally include mass and energy balances.
The process models generally include algebraic relationships which commence from thermodynamics, transport phenomena, chemical kinetics, and physical properties of the processes.
(d)
Interpretation:
The level response of the tank as a function of time is to be plotted if the inflow is returned to its original value of
Concept introduction:
For chemical processes, dynamic models consisting ordinary differential equations are derived through unsteady-state conservation laws. These laws generally include mass and energy balances.
The process models generally include algebraic relationships which commence from thermodynamics, transport phenomena, chemical kinetics, and physical properties of the processes.
