International Pumping Systems 313 Heinz Rd., Dearborn, MI 48124 To: L.A. Larson, Project Manager, First Response Technologies 91 Greentree Dr., Suite 1A, Chicago, IL 60613 From: Joshua DeBoer, Engineer Subject: Flow properties and recommended operating conditions of pump system for intended use for a new type of oxygen delivery system for emergency response personnel. Date: November 21 st , 2011 Dist: H.L. Smith, M.D., Director of Research, Respiration Division FOREWARD Your company is currently developing a new type of oxygen delivery system for emergency response personnel and requires an expert opinion on how to size our pumping components. Thus, using the provided mock-up for your system, you asked us to measure the flow properties of the pump as well as to analyze those results so that we can recommend the best operating conditions for the target system you have chosen. The target pump system would have the same proportional dimensions for inlet, outlet, and impeller dimensions, but with just an 8 mm outlet tube diameter. Specifically, you want us to document whether self-similar behavior occurs with regard to flow rate and hydrostatic head for our impeller system. Additionally, you asked us to provide a recommendation for a range of operating speeds for the impeller that can provide anywhere between 1 and 40 liters per minute of oxygen with an outlet pressure from the impeller 10% higher than atmospheric pressure. I have completed this work. The purpose of this report is to present my finding, conclusions, recommendations, and supporting documentations. SUMMARY I have completed the testing on the pump system you provided. Using dimensional analysis I found that self-similar behavior does occur with regard to flow rate and hydrostatic head for our impeller system. Due to this behavior I determined the proportional dimensions for the target
