Estimating Rainwater Run-Off and Supply Demand balance

[@sumitsimplesound6727]

This is definitely called visibility/ Insight . Simple but not simple as well. 99% can not find it or even see it but can not take it. Thanks for such fundamental issues explained so vividly with utmost care to make it Simple.

[@arora_for_life]

Very nicely explained.. you are a good teacher..

[@manjusrinivas2007]

extraordinary explanation sir. just to the point.

[@HA-vh3ti]

Can you also explain what happens if there are above avg rainy days, cause then Tank dimension may lose extra water causing deficit to annual calculation

[@googleprivacy1515]

Question 🙋 multiplying area in metre square and rain intensity in mm gives answer in litres? Don't need conversions?

[@HinrenEngineering]

Meter square multiplied by millimetre gives liters

[@ShubhankarTak]

Thank you Sir, for your Explanation. Thanks a Lot.

[@HinrenEngineering]

You are most welcome

[@ayushbhadauriya6180]

So my question is, how big tank can we put if we want to install a smaller tank than 90kL because we are simultaneously using that water too, so we'll not be able to fully fill the 90kL tank ? How can we calculate that?

[@swayamgandhi383]

You are great sir

[@rakesh74210]

Thanks sir for explaining iam not a civil engineer but I have a lot of interest in this

[@vkjkkk2k716]

Sir, first of all, many many thanks for sharing extraordinary information through your videos.. Each and every bit of information is very very useful to the society and mankind, environment... My sincere Thanks to you once again from the bottom of my heart... Secondly, a small doubt sir... I understood, how much rain water can be received in a single rain, etc. But what size of the Filtration Tank should be constructed according to the roof size. I have seen your another video, where you have constructed two compartments, of which size? and why two compartments are necessary.. I will be very thankful if you clear the doubts... Thank you in advance....🥰🥰🙏🙏

pls design of borehole for rainwater recharging pit.

great. I need a consultant in Bangladesh?? Any agent is available??

[@HinrenEngineering]

I don't know anyone in Bangladesh

Hi Sir, is this same method as rational? this means 1/360 x A x i x C ?

[@JALAJDARPAN]

Rational method is been derived based on the logic.. That is "A" is the Catchment area or drainage area contributing the flow C is runoff coefficient value which depends upon the type of landcover...so more greener the land area within the catchment less would be runoff coeffcient and due to more infiltration of rainwater to the soil "i "is the rainfall intensity.. it depends upon the time of travel of 1st raindrop to reach from the highest elevation of the catchment to the outlet point of the catchment

[@shahildays2985]

I think after learning from u, there is no need for a consultant. But I have a factory of catchment area 4500 square meter. As per ur calculation 7000 meter cubic water we can collect. But if I calculate the same reservoir area it is too big. Can I make it 20%. Because of less area I have.

[@HinrenEngineering]

For a 20 mm rainfall, the run off is 4500 x 0.8 x 20 = 72,000 liters

[@HinrenEngineering]

You have to size the tank for single rainfall or at maximum two days of rain .

[@arun4846]

Thanks sir ❤️👍🎉

[@siligurisolarstation2310]

Please tell me my city Siliguri how to calculate Very nice knowledge give me

[@JALAJDARPAN]

You can't calculate based on the city..it is estimated based on the catchment which depends on the terrain

[@stanzingyaltsen4215]

Thanks sir 😊

[@TRPGpilot]

As soon as he said measuring in 'square feet' I stopped watching. One millimetre of rainfall on 1 square metre of roof gives an output of 1 litre or water. Collected in your tank this weighs one kilogram. Its not 1923 anymore is'ts 2023 and if a video does not use metric its automatically obsolete

[@HinrenEngineering]

Well, the very next moment, while doing the calculation, it is converted into square meter .

[@TRPGpilot]

@@HinrenEngineering I do apologise, I watched again, Thank you for explaining in metric.

[@HinrenEngineering]

@@TRPGpilot In southern India , it is common to measure residential plots in square square feet.
