1
Q
What is mass balance?
A
Mass can neither be created nor destroyed
2
Q
What is meant by control volume?
A
Clearly defined boundaries
3
Q
What is steady state?
A
Equilibrium condition, no accumulation
4
Q
What is a conservative substance?
A
No reaction, reaction rate = 0
5
Q
What is a non-conservative substance?
A
Some reaction (decay or generation), reaction rate does not = 0
6
Q
What is a CMBR?
A
Completely Mixed Batch Reactor, no outflow, same concentration
7
Q
What is a CSTR or CMFR?
A
Completely Stirred Tank Reactor or Completely Mixed Flow Reactor outflow, same concentration
8
Q
What is a PFR?
A
Plug Flow Reactor, each plug behaves like a CMBR, m in and m out = 0
