This is a modern and elegant introduction to engineering fluid mechanics enriched with numerous examples, exercises, and applications. It is based on Faith Morrison's vision that flows are both beautiful and complex. A swollen creek tumbles over rocks and through crevasses, swirling and foaming. Taffy can be stretched, reshaped, and twisted in various ways. Both the water and the taffy are fluids and their motions are governed by the laws of nature. The goal of this textbook is to introduce the reader to the analysis of flows using the laws of physics and the language of mathematics. This text delves deeply into the mathematical analysis of flows, because knowledge of the patterns fluids form and why they are formed and the stresses fluids generate and why they are generated is essential to designing and optimizing modern systems and devices. Inventions such as helicopters and lab-on a-chip reactors would never have been designed without the insight brought by mathematical models.

I am not geotechnical engineer. I have a question about any availability of a computerized , fast and efficient method ,machine for possible sinkhole survey of large areas.
I know we have some books in the forum, and also I can search the internet for this , but I was just wondering if anybody have any expert knowledge about this.
I keep seeing this horrific news about , cars falling in sinkholes, half of a house and people in it disappearing, etc
Self-consolidating concrete (SCC) is an innovative material used successfully throughout the world. It is a highly flowable, non-segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation, improving the overall efficiency of a concrete construction project. SCC mixtures are highly fluid, yet their flowing properties can be adapted for a range of applications and allow practitioners to select and determine levels of filling ability, passing ability, and stability.
Self-Consolidating Concrete: Applying What We Know discusses all aspects of SCC, including:
- Benefits and limitations
- Raw material components
- Mixture proportions
- Production and quality control
- Placement and curing
Presenting a basis for consistently producing and applying SCC in a regular production environment, this book is written from the perspective of the concrete practitioner. It uses descriptions and case studies throughout, as examples of specific types of applications, to identify where the practitioner needs to focus attention.
This book bridges the gap between research and practice. It links science with practical application, describing a number of projects and types of applications where SCC has been used successfully. It will be useful for new practitioners as well as for those already using SCC.
