That would be awesome.

Yes, by all means feel free to use that descriptor.  I deal constantly with 
those who think the only difference between Process equipment and Fire 
protection is that we paint our stuff red.

Subject: [EXTERNAL] RE: Calculating Parallel fire pumps

Craig,

We use AutoSprink and I'd be happy to see if I can do that calc for you.
Not sure but think it can be done.  You can contact me off forum to discuss.

The main question I have is, can I use your description of the fire protection 
expert in future correspondences?  I deal with folks like this from time to 
time and this is the best I've seen in a long time.

Subject: Calculating Parallel fire pumps

We have a project in one of the Arab states.  We are following a little bit of 
the UFC and some of the local codes.

The owner wants two pumps selected at 50% of the required capacity instead of 
one pump as we would normally provide.  His thought is that pump 1 comes on and 
runs at 50% of it's rating and then pump two comes on and runs at 50% to meet 
the total system demand.  Yeah, I know, don't laugh.

And we've tried to talk them out of this arrangement since it will not work as 
they expect but someone who is thinks they are an expert in Quantum 
Inter-Planetary Fire Protection Hydro-Physics thinks this is a great idea.


We use HASS for hydraulic calcs and it does not have the ability calculate 
using two pumps in parallel.

Can AutoSprink or Hydracad calculate this kind of pump arrangement?
