Irricad

NEED HELP WITH THIS, I get the following errors:

1 DES 472: NETWORK IMBALANCE IN PRESSURE OR FLOW, FLOW GPM 158.8 IMBALANCE

2 DES 411: WATER SUPPLY PRESSURE NOT SPECIFIED IN WATER SUPPLY DATA

AND I DO NOT CALCULATED SYSTEM PRESSURES ON DUTY.

CAN I RESOLVE.

THANK YOU

Hi,

DES 472 : Network imbalance in pressure or flow - refer to Manual

The system is too complex for IRRICAD to handle. Try reducing the number of loops, the number of water supplies and / or the number of pipes in the network.

In some instances the network imbalance is minimal and can be ignored. Check the Design Full report.



DES 411 : Water supply pressure not specified in water supply data

The mainline analysis program cannot find a water supply pressure to use as a reference.

Select Tools|Change and highlight each water supply separately, checking to see supply has a pressure entered.

Regards!

Do you have more than one system on the design? It is unusual to have both these messages occur at the same time.

Error 472 can occur if the management is incorrect. Re-run management and double-check the correct system flows are being supplied by the required water supply.

Error 411 means that one or more of the multiple water supplies on the same system have not been assigned a pressure. For systems that contain more than one water supply a pressure must be assigned to each supply. Then after each design run modify the pressure until the required flow from each water supply is achieved.

If the issue persists please email your design to your local support - Graham Hutchinson - or ourselves (Support@IRRICAD.com).
