if we understand correctly - by adding the pumper at the hydrant - they were able to suck 4X more water (4X greater gpm) out of the hydrant you can probably think of this as a big energy equation using straight hydrant pressure - you have energy from the elevated water tank and/or the pumping station - minus the friction loss in the pipes feeding the hydrant by adding the pumper at the hydrant - you have energy from the elevated water tank and/or pumping station PLUS the energy from the pumper - minus the friction loss in the pipes feeding the hydrant apparently it is possible to get 4X more gpm out of this hydrant without wrecking the water system there might be many hydrants where this is not possible - if you have a small elevated tank that only uses a one mile long 3 inch pipe to feed the hydrant - we would not expect the pumper to get very much more gpm out of that hydrant - but we might be wrong you can almost say that the pumper at the hydrant is pushing the water 'down the hill' faster - or pulling it down te hill faster or not -- You received this message because you are subscribed to the Google Groups "massfire" group.
