(a)
Interpretation:
The grams of sodium sulfate present in the tank after 60 seconds of flow is to be calculated.
Concept Introduction:
In a system, a conserved quantity (total mass, mass of a particular species, energy or momentum) is balanced and can be written as:
Here, ‘input’ is the stream which enters the system. ‘generation’ is the term used for the quantity that is produced within the system. ‘output’ is the stream which leaves the system. ‘consumption’ is the term used for the quantity that is consumed within the system. ‘accumulation’ is used for the quantity which is builds up within the system.
All the equations which are formed are then solved simultaneously to calculate the values of the unknown variables.
(b)
Interpretation:
The mass flowrate of the solution at the exit port at steady state is to be calculated.
