Archimedes Screw Water Lifter: Angle and Speed Study

Approx. component budget: Rs. 5,000 - 9,000

Objective

Measure how the water lifted per minute changes with screw angle, speed and water level, and find the best operating point.

What you will build

A helical screw on a central shaft, set in a half-pipe trough at an adjustable angle, with a motor and speed control, a top tank and a bottom tank.

Results you can expect

• Flow rate vs rpm and angle
• Input power
• Efficiency
• Best angle and speed

What you will learn

Screw conveyors, helical geometry, fluid lifting and simple machine design, used in irrigation and wastewater.

Tools and notes

Tachometer, energy meter, stopwatch, Excel. Needs a lathe or pipe fabrication. Keep hands away from the rotating screw.

Resume points from this project

• Built and tested Archimedes Screw Water Lifter: Angle and Speed Study; objective: measure how the water lifted per minute changes with screw angle, speed and water level, and find the best operating point.
• Measured and analysed flow rate vs rpm and angle and input power; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
