Cleaning and Adjusting this information verbatim in specifications or in notes on drawings. Refer questions and comments regarding the content and use of this document to the Yale University Project Manager. A. Summary This section contains design criteria for rectangular and round metal ductwork, duct liners, and hangers for supply, return, and exhaust systems. B. System Design and Performance Requirements 1. Keep the ductwork layout simple. Use short, direct runs where ever possible, and conserve ceiling space. 2. All return/exhaust air must be ducted. The use of ceiling plenums for return/exhaust air is prohibited. 3. Perchloric acid fume exhaust ductwork must be individually ducted without connection to other exhausts. 4. Fume hoods and contaminated or hazardous areas must be exhausted by a system of ducts entirely separate from all other exhaust systems. The location of area exhausts should be carefully coordinated with reference to remoteness from supply air outlets, doors, and windows. Animal areas and toilet rooms shall have separate exhausts. See Section 00705: General HVAC Design Conditions. 5. Wherever possible, exhaust ducts carrying noxious or corrosive fumes must be under negative pressure; connect them on the suction side of the fan. 6. Review appropriate SMANCA sections (laboratory) when designing duct distribution systems.

Bogard, Supervisor Frederick Todd Davidson Atul Kohli Ofodike A. Ezekoye Michael E. Webber Variable Incidence Angle Film Cooling Experiments on a Scaled Up Turbine Airfoil Model by Kyle Feliciano Chavez, B.S.; M.S. Dissertation Presented to the Faculty of the Graduate School of The University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy The University of Texas at Austin May 2016 Dedication This document is dedicated to my family. Dad, you have always been so encouraging, helpful, and levelheaded. If not for all of your help and encouragement, I’m not sure I’d be where I’m at today. To my brother, I’m so happy for the years we spent growing up together. They are some of my fondest memories and I’ll never forget them. Mom, if you were still here today, you’d be so proud. I think of you all constantly, and I love you all. Acknowledgements I would like to first and foremost thank Dr. Bogard, who has supported and taught me so much along the way. Your dedication to your field of research is an inspiration to me, and you’ve helped shape me in to the engineer I am today. You also taught me how great it is to be “mighty fine” all the time, and that’s priceless in and of itself. -

Combat Helmets and Blast Traumatic Brain Injury
Review Articles Combat Helmets and Blast Traumatic Brain Injury Duncan Wallace, FRANZCP and Stephen Rayner, DPsych (Clinical) Abstract: Background: The conflicts in Iraq and Afghanistan and the prominence of traumatic brain injury (TBI), mostly from improvised explosive devices, have focused attention on the effectiveness of combat helmets. Purpose: This paper examines the importance of TBI, the role and history of the development of combat helmets, current helmet designs and effectiveness, helmet design methodology, helmet sensors, future research and recommendations. Method: A literature review was conducted using search terms – combat helmets, traumatic brain injury, concussion, Iraq, Afghanistan and helmet sensors, searching PubMed, MEDLINE, ProQuest and Google Scholar. Conclusions: At present, no existing helmet is able to fully protect against all threats faced on the battlefield. The prominence of traumatic brain injury from improvised explosive devices in the current conflicts in Iraq and Afghanistan has highlighted the limitations in knowledge about blast and how to provide protection from it. As a result, considerable research is currently occurring in how to protect the head from blast over-pressure. Helmet sensors may provide valuable data. Some new combat helmets may be able to protect against rifle rounds, but may result in injuries occurring behind body armour. Optimal combat helmet design requires a balance between the need for protection from trauma and the comfort and practicality of the helmet for the user to ensure the best outcomes. Keywords: combat helmets, traumatic brain injury, concussion, Iraq, Afghanistan. No conflicts of interest were identified by the authors. Introduction Role and history of combat helmets Recent adverse media attention about combat The primary role of the combat helmet is to protect helmets used in Afghanistan by United States the soldier’s head against injury. -

23.31.00 Ductwork
UNIVERSITY OF PENNSYLVANIA Design Standards Revision July 2019 SECTION 233100 – DUCTWORK 1.0 Acoustical duct lining in any part of the duct system is prohibited. All ductwork requiring insulation shall be externally insulated (Refer to the Sheet Metal Ductwork Insulation Schedule in Section 230700 for insulation types and thickness). Double walled ducts consisting of an outer wall of galvanized sheet metal, an inner wall of perforated galvanized sheet metal with insulation sandwiched between the layers is permitted. 2.0 All ductwork shall be designed, constructed, supported and sealed in accordance with SMACNA HVAC Duct Construction Standards and pressure classifications. When the ductwork pressure classification of these standards is exceeded, construct ductwork in accordance with SMACNA Round and Rectangular Industrial Duct Construction Standards. The following preferences or modifications to the Standards shall be specified: A. Radius elbows with a construction radius of 1.5 the duct width are preferred to square elbows. B. All square elbows must be constructed with single thickness turning vanes, Runner Type 2 as shown in Figures 4-3 and 4-4 of SMACNA Duct Construction Standards - Metal and Flexible. Where a rectangular duct changes in size at a square-throat elbow fitting, use single thickness turning vanes with trailing edge extensions aligned with the sides of the duct. C. Air extractors and splitter dampers are not permitted. D. Transitions and offsets shall follow Figure 4-7 of SMACNA HVAC Duct Construction Standards - Metal and Flexible, except that sides of transitions shall slope a maximum of 15 degrees. E. Minimum duct gauge shall be 22 for ducts up through 43", 20 gauge up through 60" and 18 gauge above 60". -
Myths and Mythtery of Air Flow Do Not Be Swayed by Misconceptions About Air Flow in the Industry
Myths And Mythtery of Air Flow Do not be swayed by misconceptions about air flow in the industry. By R.B. (Buzz) Est E s , C M s n HVAC system cannot function optimally or properly unless the duct system is properly designed and installed. AToo often customers buy “high efficiency” systems that do not deliver the energy-saving performance because of a defi- cient duct system. This is usually because many contractors “design” systems based on ignorance and superstition instead Discerning fact from fiction is half the battle to under- of correct knowledge of air flow.
