borewell dug 300ft went dry immediately, blasted it and water was availabel at 200ft depth, now 13ft depth how

Send down a SCUBA diver to look!  Just kidding.  Your idea to pump out the well and see what happens sounds good.  If you have a camcorder, you could tie it to a rope and lower it to the bottom to have a peek like in the movie Volcano.

The guy who said no, is full of crap. You can use it, but you have to ask yourself if it's worth it. If it's one of those 8 foot long 1 foot deep jobbies, it might be better to just dump it and start again. If you go overboard on the chlorine it won't be nice to be in.\n Eventually, no matter how much you may not want to, you will HAVE to dump that water. The chlorine added will just buy you a little time is all.

The canals I've seen around here are U shaped with a wide and flat bottomed u as it were...\n\nI would imagine it all has to do with how you did your canal, obviously the middle has to be deeper than the sides so that the water stays in the canal...

stick it in a tank of water then measure the water displaced.archemedes law

We certainly have had our share of rain.. I've been pumping out my cellar for nearly two months!  Rt 1 was closed last week for flooding. CERT (the community emergency response team) has been called to action twice so far, just to help with flood control. \n\nNo need to worry though, all in all we're doing OK.

You are describing "water hammer."\nIt happens when a valve is closed in an old building or one that has not been plumbed according to code.\nEven in a relatively short run of 5 meters, a 2 cm pipe will contain 1,000 cc of water.  That much water weighs a kilogram.\n(15 feet, 3/4 inch, 2.2 pounds)\nThe water in the pipe is moving fairly quickly and with that much mass it bashes the building with a lot of force.\n\nKnowledgeable plumbers are aware of the problem and install short lengths of pipe that stay filled with air.  You may have noticed one around a construction site.  Near a sink or other place that has a valve, there will be a short length of pipe that comes up to a closed cap.  It looks like the plumber wanted to run the line somewhere else and decided against it.  The air in that pipe will compress and absorb the shock to eliminate water hammer.\n\nZeedo is right.  Ideaquest and Peter are not.  Trapped air solves the problem.

The answer is (d) if this is the question:\n\nInitially the tank is full.  The outlet pipe is opened.  When the water in the tank is 3/4th full, both inlet pipes are opened.  Calculate the fractional level of the water in the tank after 2:05 hr.\n\nSince inlet A and outlet C cancel each other out at 50L/hr, only need to consider inlet B at 25L/hr.  Since 2:05 hr is the same as 2.083 hr (5 min = 0.083 hr), the amount of water added by inlet B is 25L/hr * 2.083 hr = 52.08 L.  Will use 52 L in the calculation.\nThe total amount of water in the tank after 2:05 hr is the initial 750 L + 52 L = 802 L.\nThe fraction level of the water is 802 L / 1000 L = 0.802\nSince 4/5 = 0.8 the answer is (d).

you can't get any sand from it. because height means distance above the sand. so for 1400ft depth only we can get sand man

cause wat makes the wet stuff come out is around the entry way of the hole

Let the height be h (inches), radius r.\n\nNow by proportion, h = 5r at every level.\n\nHence volume is given by\n\nV = (1/3)pi*r^2*h which is\n       (5/3)*pi*r^3\n\n"Rate at which water is drained" means find dV/dt\n\ndV/dt = 5*pi*r^2*(dr/dt),\n\nand dr/dt = (1/5)*(dh/dt)\n               = -2/5\n\nYou can finish from there.

have your water tested, it could be a virus, a bacterium, or even lead...have it tested ASAP

u also filled any air pocket that might have been in the dirt prior to digging it so buy filling in those pockets it made it seem like u ran out of dirt and not able to fill the hole

it was dug out of the ground\n\nsee - the next two answers just confirm what i said, in a very wordy way

I think this guy is trying to grow something hydroponically and doesn't want anyone else to detect it.  Know Your Enemy.  At any rate, since there is so much water, there probably will be an increase in vegetation around the object in question.  As far as the difference in temperature, since water is a great heat sink, the water would probably end up being about the same temperature as the surrounding soil.  When you get more than 3 ft deep (Except in possibly extreme climates) the soil temperature stays about the same year round.  The sun just can't warm and the air just can't cool the soil fast enough for the underlying substrates to be affected.  This is why when utilities (gas, electric, water, etc) are buried, there is a minimum depth for the conduit to be below the ground so that changes in temperature will not affect the performance and/or integrity of the circuit, in addition to the fact that the average guy can't just come along with a shovel and damage it.  One thing that may affect the temperature of the buried object is how well the soil it was buried in was placed around the object (i.e. the density of the soil placed).  If the area was just backfilled with no attempt to pack the soil, the soil would have large pockets of air in it which would allow it to not only retain the heat it has, but also settle relative to the surrounding natural soil.\n\nI hope this helps.

Use a water level:  \nTake a long piece of hosepipe, put a short length of clear tube in each end.  \nFill with water and with a friend lay the pipe along the ground with the open ends (with the clear tube pointing upwards).\nThe water in the clear tubes at each end will be at the same height.

Wire logging is after the hole is drilled, different tools are sent down to the bottom of the hole. the tools are raised back to the surface very slowly. These tools gather different type of info down the well (gas pressures, geology formations, depth, tempurature and a lot more that I cannot explain). As for perforationI hav no experience with that,so I cant help you.
