PVC pipelines Inquiry (采购产品): PVC pipelines Hello, I am a student at the University of the South Pacific. I am doing a research for the Material flow analysis on on pipe lines. I am seeking your kind help for information on water pipes. My research contributes to solid waste disposal in Pacific Islands. So I am trying to find ways where to convert solid water pipes waste into other products. I am asked to research all the materials pipelines are made off. The purpose is to explain the reliable distinction between stocks and flows that is a prerequisite for empirically determining whether a socio-economic system is still ?growing“ (in physical terms), is in a steady state, or is shrinking. Flows are linked to a time period (week, month, year). Stocks refer to the size of the population and the weight of the infrastructure. Accordingly, an operational distinction between ?size“ and?metabolic rate“, as well as between the ?growth rate“ and the energetic and material?turnover“ of the social system can be defined, and the indicator ?net addition to stocks“ can be calculated. In addition, I am also interested in the: volume, sizes, sources, energy consumption, weight and ranges of water pipes. However, I need informatioin on how to process water pipe lines. I hope you will answer me back. Yours faithfullness, Lewis Hunt. **** Hidden Message ***** Lewis Hunt 769 FJI Company: University of the South Pacific E-mail: leewis_fania@yahoo.com **** Hidden Message ***** leewis_fania@yahoo.com |
