Water

architects and engineers are turning to a new, more economical way of cooling and heating large buildings: The YORK® Absorption Chiller. From an environmental standpoint, the YORK® Absorption direct fired chiller is a vote for the Earth. By using water as its refrigerant and lithium bromide as the absorbent, the ozone depletion potential is zero. rEliablE products with long-tErm, low cost of ownErship YORK® Absorption chillers are designed, manufactured and tested in a state-of-the-art…

c05.qxd 10/29/07 1:18 PM Page 316 316 Chapter 5 Distributed Forces Sample Problem 5/18 A rectangular plate, shown in vertical section AB, is 4 m high and 6 m wide (normal to the plane of the paper) and blocks the end of a fresh-water channel 3 m deep. The plate is hinged about a horizontal axis along its upper edge through A and is restrained from opening by the fixed ridge B which bears horizontally against the lower edge of the plate. Find the force B exerted on…

Chinese Academy of Sciences, Beijing 100049, China Abstract: A group of constructed wetlands (CWs) were applied to the recirculating aquaculture system. This study assessed the performance of CWs in treating the aquaculture wastewater, examined the water quality condition of aquaculture ponds and the growth and the survival rate of “target” species (Ictalurus punctatus and Megalobrama amblycephala). The results showed that CWs were effective on reducing the concentrations of 5-day…
