Construction Engineering & Management - Vol 2
The chapter delves into various types of pile driving equipment, emphasizing the mechanics and selection criteria for each type of hammer based on soil conditions and pile specifications. It discusses drop hammers, single acting and double acting steam hammers, highlighting their operational principles, advantages, and relevant safety considerations during pile installation.
Abraham
Fluid Mechanics - Vol 2
This chapter covers the fundamentals of flow in noncircular conduits and multiple path pipe flows, detailing key concepts such as the use of hydraulic diameters and roughness in water flow. The historical context is provided through significant experiments from the 1930s that laid the foundation for modern fluid mechanics, including the relationship between friction factors, Reynolds numbers, and wall shear stress. The chapter also explores how to quantify energy losses in varying conduit shapes and flow conditions.

Hydraulic Engineering - Vol 2
The chapter focuses on pipe networks and evaluates factors affecting fluid flow through pipes, particularly the calculation of head loss due to friction. The importance of friction factors and how they relate to Reynolds number and relative roughness is discussed, with a highlight on using the Moody chart and empirical formulas. Additionally, it covers the significant differences between major and minor losses in pipe flow.
Abraham
Disaster Preparedness & Planning - Vol 4
The chapter discusses the complexities of community recovery in disaster contexts, highlighting the challenges posed by insecurities in land tenure and dependency on external institutions. It emphasizes the significant roles of women in recovery, the impact of poverty, and the mixed outcomes of community participation efforts. Key lessons include recognizing the need for self-esteem and active contributions from community members rather than reliance on paid support or charity.
