Solving For Theoretical Mean Residence Time ## Inputs:

reactor volume (V)
flow rate (Q)

## Conversions:

reactor volume (V)
= 0
= 0
meter^3
flow rate (Q)
= 0
= 0
meter^3/second

## Solution:

theoretical mean residence time (tR)
= NOT CALCULATED

Step input for completely mixed or
continuously stirred tank reactor CSTR
Pulse Input for completely mixed or
continuously stirred tank reactor CSTR
Plug Flor Reactor PFR  step input: when t < tR, C = 0 when t >= tR, C = C0 pulse input: when t = tR, C = C0 when t < tR, C = 0 when t > tR, C = 0

Where
 tR = theoretical mean residence time V = reactor volume Q = reactor flow rate C = concentration at time C0 = initial concentration Cn = concentration at tank n t = time n = number of tanks
