Hi Russ! The formula for pressure instead is equal density x gravity x height (1,000 x 10 x 20) giving a pressure value of 200,000 kg/ms2. Yes, in my calculations the Pump Input Power and Generator Output Power are the same if the Pumping Time is the same with the Generating Time. But what if...

I used the formula of Pressure = mass x gravity x height

Considering my understanding of projectile motion, it should be the same. Glad to be corrected if I'm wrong. =)

Finally, I got what I was looking for! It made me easier to understand seeing some figures like this, thanks Guineafowl! Thanks to all of you guys! Good days ahead!

You're right and I believe also that there are flaws in my understanding of this concept that's why I want to figure out with the help of you and other experts. But I prefer to based my understanding in mathematical figures rather than just telling myself it's WRONG because that's what I've...

Hi Dave! Thanks to your inputs. That's what mainly confuses me and I know it will never ever be 100% efficient for the pump. Considering that the pump is too inefficient that instead of only 0.33W input power, it uses 3W. But the power generated is 3.33W, so does it mean there's still 0.33W...

Thank you guys for your comments and suggestions, upon recalculations, I came up with this clearer query. If a 1-liter water is elevated by 20 meters, it will have a Potential Energy of 200 Joules. When I use a Water Pump to elevate that 1-liter water at 20 meters, it will require a Work of 200...

Hello there! So confused here, I tried to do some calculations with my power generation experimention. In terms of energy input, the energy output is lower. But in terms of power input, the power output is way larger. Thanks in advance! Cheers!

Appreciate your inputs, will try to do more basic calculations to share with you for your comments and suggestions. Thanks!

Let's consider the formula of Work = Force x Distance (elevation). For Top Refilling it will be Less Force - High Distance, it is lesser Force because the discharge port is atmospheric pressure. And the static pressure is negligible if we use smaller diameter water pipes. For Bottom Refilling...

Appreciate this and will do calculations by considering this methods. Will share with you the results.

Thanks for your response. The objective is only to top up the water tank to keep the water level.

Based on my understanding, Top Tank Refilling Advantage: Atmospheric Pressure Disadvantage: High Head (Requires more distance, thus more Work since W = f x d) Bottom Tank Refilling Advantage: Low Head Disadvantage: High Static Pressure (Requires more Force, thus more Work since W = f x d)...

Indeed, solar and wind turbine are cheap but it still it have disadvantages like it's only effective when the sun is shining, wind is blowing, consumes significant footprints, etc. Just want to make it clear that my proposed project won't compete with solar and wind turbine but rather to...
