Pulse Input for completely mixed or
continuously stirred tank reactor CSTR

	concentration
	initial concentration
	time
	theoretical mean detention time
	concentration at n tank in series

Plug Flor Reactor PFR

step input:
when t < t_R, C = 0
when t >= t_R, C = C₀

pulse input:
when t = t_R, C = C₀
when t < t_R, C = 0
when t > t_R, C = 0

Where

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