Concise Catalog of Deep-sky Objects


Book Description

Here is a unique and fascinating reference book for every serious deep-sky observer! Entries for each of more than 500 deep-sky objects provide far more than the usual astronomical data – they also detail, in every case, the most interesting facts. Physical factors, astrophysical information, evolution, unusual features, the list is endless. The objects are all listed in NGC order. Astronomers can now get an insight into exactly what they are looking at, to add a new level of insight and enjoyment to deep-sky observing.




Tables for the Hydraulic Design of Pipes, Sewers and Channels Volume II


Book Description

Covering conduit and channel shapes by tables of properties based on unit size, this work also includes detailed coverage of the possible effects of variation in water temperature within the normal water resources, as well as considering the treatment of part-full flow in circular pipes.




Tables for the Hydraulic Design of Pipes, Sewers and Channels


Book Description

This new edition again includes the extended range of pipe size that covers European standards as well as those for the newer materials now widely adopted in the UK. The book's main objective is to aid Colebrook-White assessments of resistance in such pipes and in a great variety of free-surface circumstances including large rivers.







Observing the Caldwell Objects


Book Description

The objects listed in the Caldwell Catalogue supplement Messiers famous catalogue of 110 non-stellar objects, and include some of the most fascinating objects for amateur astronomers. This comprehensive guide has been produced specially for observers, with each object conveniently shown on a double-page spread. There is a photographic image of every object and full technical data including position and NGC number. It also includes a finder map showing TelradTM circles, a star-hopping guide, a visual description of each object as seen through amateur telescopes, and a physical description of the object itself. Finally, there is a fold-out map showing the location of all the Caldwell objects in the sky. A practical and essential guide.

Construction Materials


Book Description

Exhaustive list of materials used in construction and architecture. Inforamation on each category includes history and manufacture, the physical and chemical properties, and the conditions of use. Although an American publication all measurements in the book include metric equivalients.




Additional Tables for the Hydraulic Design of Pipes, Sewers and Channels


Book Description

The aim of these tables is to overcome limitations in the existing Hydraulics Research "Tables for the Hydraulic Design of Pipes and Sewers". The current edition of the tables is limited to pipe diameters of two metres and to a couple of pipe shapes. The additional tables which are designed to be used in conjunction with the existing 5th edition of "Tables for the Hydraulic Design of Pipes and Sewers" would extend the diameter to 20m. New interpolation procedures for part-full pipes and pipes of other cross-sectional shapes, other than circular and one particular form of egg-shape can be determined.
