is used to investigate channel flow‚ hydraulic jump‚ determining the coefficient of discharge flow of the system. The second equipment was air pipe assembly and oil pipe assembly‚ for the air pipe it is used to determine friction losses in pipe and discharge‚ oil pipe it is used to determine if the flow is laminar or turbulent‚ velocity distribution in pipes. The other equipment were the closed circuit wind tunnel‚ it determines the pressure distribution and velocity distribution around various bodies

In a conventional system‚ the pressure decreases as pumps are stopped. The reduction in pressure may result in the well taking a kick‚ wellbore collapse or differentially stuck pipe. Furthermore‚ when circulation is stopped‚ drilling fluid forms a gel‚ which requires an increase in pressure to be broken down when pumps are resumed. In static conditions‚ drill cuttings have a chance to collect at the bottomhole assembly (BHA).

Ahmed M.Ashraf Governance 2010 1- Overview of Lesotho Highlands Water Project South Africa is a water scarce country and its neighbor‚ Lesotho is a water rich country categorized by high annual rainfall. South Africa in view of its increasing demand for water in the Guateng region (regarded as the heartland of South Africa) realized the water is going to be scarce in future1. The idea of transfer of water from water rich area (Lesotho) to the water scarce area (Gauteng‚ S.A) was conceived

What is the difference between Pipe and Tube? Ans: Pipe is identified by NB and thickness is defined by Schedule whereas Tube is identified by OD. 6. From which size onwards NB of pipe is equal to OD of Pipe? Ans: From the size 14” and onwards NB = OD of pipe. 7. Write down the outside diameter of following pipe? i. 3 inch ii) 6 inch iii)

experiment: Head loss due to friction and pipe fitting in round smooth pipe Introduction To verify that Darcy – Weisbach equation can be used to predict the head loss due to friction with of water through a smooth bore pipe. Apparatus HF 135 Piping Loss Test Set. Summary of theory For water flowing through a circular pipe‚ the head loss due to the friction can be calculated using Darcy – Weisbach equation.

Products Industry (SIC code 325) are primarily engaged in using different types of clay and other additives to manufacture brick and structural clay tile‚ ceramic wall and floor tile‚ clay firebrick and other heat-resisting products‚ and clay sewer pipe. The mining of clay used to make structural clay products are not included within SIC code 32. The U.S. Bureau of Mines categorizes clay into six groups: ball clay; bentonite; common clay and shale; fire clay; fuller’s earth; and kaolin. Ball clay
