Design and Construction Guidance for Breakaway Walls ...apse under wind and water loads without causing collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system. In addition, like all other construction in the Special Flood Hazard Area, any enclosure below the lowest floor of an elevated building must be built with flood-resistant materials and with methods and practices that minimize  more...

HVAC Tips for Green Buildings Overview Buildings as they are designed and used today, symbolize unrestrained consumption of energy and other natural resources with its consequent negative environmental impact. According to the Department of Energy, in 2005, commercial buildings accounted for 35 percent of total electricity consumption. Roughly 40-50 of the total electricity consumption is accounted for by HVAC systems,  more...

The student is expected to read and review the material contained in the Initial Evaluation of Displacement Ventilations and Dedicated Outdoor  more...

Centrifugal and Positive Displacement Pump Fundamentals ... divided into two major categories - kinetic and positive displacement. Kinetic pumps can be further subdivided into centrifugal pumps (the vast majority of kinetic pumps) and special effects pumps. Jet pumps, reversible centrifugal, gas lift and electromagnetic are examples of special effect pumps, which are not covered in this course. The operating principle of centrifugal pumps and positive  more...

Pumps ...ting ranges and problem areas of centrifugal and positive displacement pumps. The discussion on centrifugal pumps covers impeller types, capacity ranges, material selection, and suitable operating conditions. Problem areas are discussed, such as cavitation, low flow, vapor bind, reverse rotation and high flow. The course author, who has over 40 years of experience designing and troubleshooting  more...

Theory and Application of Reciprocating Compressors ... applications, characteristics, and operation of positive displacement (reciprocating) compressors. This course is oriented toward engineers involved in specification, selection, application and operation of gas compressors. The presentation concentrates on large industrial compressors as in natural gas transmission and process plants, but is applicable to all reciprocating compressor units.  more...

Liquid Pipeline Hydraulics ...hrough a pipeline is calculated. Centrifugal and positive displacement pumps are discussed along with an analysis of the pump performance curves. The impact of liquid specific gravity and viscosity on pump performance is explained with reference to the Hydraulic Institute charts. The use of drag reduction as a means to improving pipeline throughput is explored. Batching of different products in  more...
