2. 2 TABLE OF CONTENTS 1.0MARKET DEMAND (Identification of human need) Water requirements for students and staff at Main Campus of University of Nairobi 2.0DEFINITION OF PROBLEM (Specification of requirements to be met by the design) Quantity of water required, determined from population and per capita consumption Pressure (total or dynamic) head to be overcome by pumping system. This is determined from (1) total static head (elevation of suction point relative to delivery point), and (2) friction head loss (pressure loss due to fluid friction in pipeline). The first element of pressure depends on site conditions as in terms of location of water source and desired delivery point. The second element of pressure depends on the pipe size and material selected. Only static head need be determined at this stage. 3.0POSSIBLE SOLUTION (Concepts to be considered) –An existing municipal supply –A new borehole supply to replace existing supply 4.0PRELIMINARY SELECTION OF PIPE SIZE TO MEET DEMAND 5.0AVAILABLE PIPE MATERIALS AND STANDARDS 6.0PIPELINE CHARACTERISTIC CURVE (Review of theory)) 7.0CHARACTERISTIC CURVE FOR THE SELECTED PIPELINE (Actual) 8.0SELECTION OF PUMP TYPE 9.0SELECTION OF PUMP 10.0SUCTION ARRANGEMENTS AND DESIGN 11.0SURGE PRESSURE AND SURGE CONTROL
