With reference to solar water pumps, consider the following statements:1. Solar power can be used for running surface pumps and not for submersible pumps.2. Solar power can be used for running centrifugal pumps and not the ones with piston.Which of the statements given above is/are correct?
✓ Correct answer: d) Neither 1 nor 2
ExplanationStatement 1 is incorrect: Solar power is capable of operating both surface and submersible pumps.Surface Pumps are installed above the water surface and are suitable for applications where water is drawn from shallow sources.They can be effectively powered by solar energy.Submersible pumps are designed to operate underwater.These pumps are ideal for deep wells or boreholes.Solar-powered submersible pumps are widely used for extracting water from significant depths.Statement 2 is incorrect: Solar power can be utilized to run both centrifugal and piston (positive displacement) pumps.Centrifugal Pumps are commonly used in solar applications for higher flow rates with lower lift.They are efficient when adequate solar power is available.Piston Pumps also known as positive displacement pumps, piston pumps are suitable for applications requiring high lift with lower flow rates.Their ability to maintain efficiency under varying conditions makes them well-suited for solar-powered systems.UPSC GS Paper-I PYQs 572 SUPER HINT Solar power is just a source of electricity.It can power a
