  1. WATER PUMPING SYSTEM DESIGN REPORT

  2. TABLE OF CONTENTS • TABLE OF CONTENTS • 1.0 MARKET DEMAND (Identification of human need) • Water requirements for students and staff at Main Campus of University of Nairobi • 2.0 DEFINITION 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. • 3.0 POSSIBLE SOLUTION (Concepts to be considered) • An existing municipal supply • A new borehole supply to replace existing supply • 4.0 PRELIMINARY SELECTION OF PIPE SIZE TO MEET DEMAND • 5.0 AVAILABLE PIPE MATERIALS AND STANDARDS • 6.0 PIPELINE CHARACTERISTIC CURVE (Review of theory)) • 7.0 CHARACTERISTIC CURVE FOR THE SELECTED PIPELINE (Actual) • 8.0 SELECTION OF PUMP TYPE • 9.0 SELECTION OF PUMP • 10.0 SUCTION ARRANGEMENTS AND DESIGN • 11.0 SURGE PRESSURE AND SURGE CONTROL
