5. Overview explanation Icon Description
Mass transfer indicator: direction
Mass transfer resistance to set standard gas inflow
Optional mass transfer resistance, i.e. filters
Location of interest, area with pressure and volume
Compressor to set mass outflow
Lab 2,02

6. Assumptions
Each room is seen as a CSTR  to pressure variation within a room
All mass transfers are pressure driven
The hallway has a constant pressure: 1atm
No air leakage from outside into the laboratories
All laboratories are connected to the hallway, and only to adjecent laboratories

7. Equations dV(n)/dt = Σ(V_in(n))-Σ(V_out(n))
Where: V = ((P_out-P_in)-P_drop)*A*Kw
P = pressure in the area (Pa)
A =the surface area where gas can flow through (m2)
Kw = the resistance parameter (m/Pa/s)
n = the time step for the calculation
A resistance (P_drop) is to be defined as pressure drop (Pa)
The pressure in an area is calculated as: P(n) = P(n-1)+(V(n)/V_area*PC)
Where PC = pressure conversion coefficient (Pa/bar)

8. Constants required Area volumes (m3)
Total gas inflow at the beginning (m3/s)
Gas distribution to laboratories  mass transfer resistances ( ) (Pa)
Standard gas outflow (pump capacities, m3/s)
Gas resistance parameters for transport beween laboratories and hallway (kw,m/Pa)
