Irricad

Olá.

Fiz um comparativo, realizei o calculo de uma tubulação com múltiplas saída em uma planilha do Excel e em outro programa chamado hydrocal e também calculei a mesma tubulação no Irricad.

Os resultados apresentaram diferenças significativas, as perda de carga na planilha e do hydrocal parecem ser bem maiores quando comparadas com os resultados do irricad.

Estou calculado cada trecho separadamente usando a seguinte formula "'=(10,64/(D.I^4,87))*((Q/140)^1,852)".

Os resultados da planilha e do hydrocalc estão em torno de "33 m Headloss" e no Irricad "18 m Headloss"

No anexo "Report Irricad" no "Pressure End" comparando com a coluna do Excel "P. Entrada No gotejo" o resultado final tem um diferença de quase 15 m

Poderia explicar melhor como o Irricad trabalha e como ele calculas as perdas de carga?

Thank you for your question.

The IRRICAD calculations have been rigorously checked and field tested over many years.
There could be several reasons why you are seeing differences which we can only comment on after reviewing your IRRICAD design and database. Please email to Support@IRRICAD.com .

To clarify, are you using a Hazen-Williams roughness factor of '140' for all your pipe sizes in the Excel spreadsheet and Hydrocalc?

The IRRICAD Team

Obrigado pela rápida resposta.

Vou enviar o e-mail para o suporte e revisar o fator de rugosidade Hazen-Williams de '140'.

Hi Mr. Oliviera
from what I checked in example with your data I get very similar results that you show in the HydroCalc application
But when I checked your example from the report it is not with the same sections of pipe diameter lengths between 100mm , 75mm , 50mm & 35mm .
I suggest that you will check again your teste example

Hi Irricad Team,

I, would like to know why I am blocked to post new topic in forum?

Hi Dan, it's actually not an issue. That happen is that can't create a new question on the forum, as there isn't that option for me.

What e-mail?

I understand it's a problem you're having with the forum, but in order to not further added unrelated posts to this topic, could you please email 'support at irricad dot com' with a description of your Forum problem. When does it occur? What do you see? Any error messages?

Thanks!
