1. Tube well pump using wind power Nishan Madushanka HND/CV/03/12

2.  The specialty in my windmill is that it pumps water from the tube wells by taking only the mechanical power from the windmill. Introduction

3. Pumping water should suitable for agriculture purposes Pump water up to 10m water Storage and storage capacity Most cost effective pumping system Does not rely on non-renewable resources Portable Durable Easy and very little maintenance Easy to install the site Safe to environment Water pumping capacity Customer requirements

4.  Turbine Type - Horizontal Axis  Rotor diameter - 3.3 m  Nos. of blades – 8  Blade material- fiberglass  Tower height – 10 m  Cut in wind speed –9 km/h  Rated wind speed – 18 km/h  Estimated Water output – 1000-800 litters per hour  Depth of tube well – 30ft Specifications

5. Conceptual Designs - 1 Windmill generate the electricity and water pump disadvantage High Operating Costs Cant pump more water Parts are expensive wind power is down to the winds unreliability factor Advantage take up very little space for Installation Low cost to generate power Environment friendly

6. Conceptual Designs 2 Use vertical turbine Advantage Low cost to generate power Environment friendly can be placed lower to the ground maintenance easier and lower the construction costs disadvantage less wind speed is available to blade break down or collapse during high winds

7. Conceptual Designs 3 Advantage little maintenance and wind is free take up very little space for Installation Can pump more water Can storage water provide water tank Lower capital costs due to simpler design Disadvantage Wind speed depend on weather

8. Selection of the optimum design Selection of ideal design solution Design 01- high cost, Easy maintain, minimum water pump Design 02- Low cost, Easy maintain, minimum water pump Design 03- Low cost, Easy maintain, Medium water pump. Finally I Chosen 1 st design because of fulfil customer needs and sustainable design.

9. Engineering Design Wind speed analysis of data relating with wind through checking practically with Anemometer. Monthly wind speed pattern in Puttalam Region.

10. Engineering Design Calculation of Wind Power Power in the Wind = ½ρAV3 –Effect of swept area, A –Effect of wind speed, V –Effect of air density,  Swept Area: A = πR 2 Area of the circle swept by the rotor (m 2 ).

11.  Balance of gyroscopic forces  More aesthetic, less noise, fewer bird strikes  Blades easier to install Engineering Design Number of Blades Blade Composition Material- fiberglass Lightweight, strong, inexpensive Most modern large turbines use fiberglass

12. Engineering Design Blade shape Airfoil Shape similar wings of an airplane, wind turbine blades use the airfoil shape to create lift and maximize efficiency. The Bernoulli Effect

13. Engineering Design Tower Raises turbine into the air Ensures blade clearance Types Free standing lattice (truss) Cantilevered pipe (tubular tower )

14.  this design is designed for Hambantota, Puttalam and Anuradhapura area.
