tolleranza sulla portata di flusso rete idrante Explanation: questa è la mia ricerca e la mia proposta in base a tutto quello che ho letto ricerca in base ai dati hose stream allowance of 250 gpm ..... qui si fa più volte rif. alla norma NFPA Portata nominale di flusso: 2” (DN50): 0 - 250 GPM (0 - 946 l/min) 3” (DN80): 0 - 550 GPM (0 - 2080 l/min) https://www.tyco-fire.com/TFP_translate/TFP1580_IT.pdf Distribution System Requirements for Fire Protection https://books.google.it/books?isbn=0898679354 1998 - Technology & Engineering Required fire flow for sprinklered properties consists of the flow required for sprinklers, including a hose-stream allowance or 500 gpm (31.5 L/s), The Whys Behind FM Global Data Sheets 2-0 and 8-9 - SFPE https://www.sfpe.org/page/2012_Q2_4? *****The design of 8 @ 40 (2.8) has a hose stream allowance of 250 gpm (950L/min) and a duration of 60 minutes when the maximum linear spacing is up to 12 ... Inoltre pressioni elevate sulle reti idranti possono dar luogo alla ingestibilità della manichetta e della lancia. ..... le tolleranze sulla prevalenza e sulla portata ..... La norma NFPA 20, che per le tolleranze prestazionali rimanda alle Hydraulic Instituite, https://www.edilizianamirial.it/pompe-antincendio-gruppi-di-... From NFPA 13, 2013: A.11.4.2 The hose stream demand required by this standard is intended to provide the fire department with the extra flow they need to conduct mop-up operations and final extinguishment of a fire at a sprinklered property. This is not the fire department manual fire flow, which is determined by other codes or standards. However, it is not the intent of this standard to require that the sprinkler demand be added to the manual fire flow demand required by other codes and standards. That should explain pretty well what the hose stream allowance is. https://www.eng-tips.com/viewthread.cfm?qid=356133 |
