### 9.2.3. Table of pipe-runs

The “Pipe-runs” table displays results for all pipe-runs in the system assigned to particular sources. The type and name of the source is displayed at the top. This is followed by results for ungrouped components, then by results for components of groups.

PT | type of pipe-run: supply or return |
Pipe-run symbol | symbol (name) of pipe-run specified by user or assigned automatically |
Connection pipe-run symbol | symbol (name) of pipe-run to which the given pipe-run is connected – assignment is made automatically during diagnostic run |
Q/F | quantity of heat carried by pipe-run | [W]
Diam. | diameter of pipe-run calculated or specified by user. User-specified diameter is displayed in results in square brackets | [mm]
L | length of pipe-run | [m]
R | friction resistance | [Pa/m]
z | total pressure drop caused by fittings | [Pa]
R*L+Z | total pressure drop on pipe-run, excl. control fittings | [Pa]
Press. drop | total pressure drop on pipe-run, incl. control fittings | [Pa]
w | velocity of medium in pipe-run | [m/s]
G | flow rate of medium in pipe-run | [kg/h]
Insul.th. | thickness of insulation | [mm]
dt | water temperature drop in pipe-run | [K]
t/q.inlet | temperature at inlet of pipe-run | [0C]
q | specific heat loss in pipe-run | [W/m]
Qpr/Fpr | heat loss in pipe-run | [W]

The line with results for a pipe-run is followed immediately by a line with results for fittings installed on that pipe-run.

Valve name | type of valve (catalogue name) |
Diam. | valve diameter | [mm]
Press. drop | pressure drop on control component | [Pa]
Xp | value of proportional control deviation (for some valve types) |
Va | valve authority (for some types of valves) |
Setting | sized setting or plate orifice |

Below is the table of manifolds with the following fields:

Manifold Symbol | symbol of manifold |
Conn. PR symbol | number (symbol) of connection pipe-run |
Heat flux Q/F | heat flux carried across manifold | [W]
Flow rate | mass flow rate in manifold | [kg/h]
z | local pressure drop | [Pa]
t/q inlet | temperature of medium at manifold inlet | [0C]
No. of outlets | number of outlet ports in manifold, including spare ports, specified in data table |
