somebody says PH=8 as it is at the end HCl 10^-8 M

but it can get basic by adding acid

Water must to be pumped from a well 120 meters bellow ground level to a tower 5 meters high, once there the water falls freely to a 24,000 liter tank. In the well a typical centrifugal pump is put hanging at three meters over the water level and with six meters of a two inch diameter pipe for suction, and for pumping a two inch diameter pipe is to be used . What is the work done by the pump when 20,000 liters have been served to the tank; what is the power of a pump selected to do this work in 60 minutes.

algae-3m-6m-9m

red----70--25--13

green-56--35---9

blue--132--55--12

this is how the depth and algae (grams/gallon) was found distributed

Work done in water pumping?

Water is to be brought from a well 60 meters bellow ground level to a tower 10 meters high, once there the water falls freely on a 5000 liter tank. A submerged pump 10 meters under water level and a two inch diameter pipe is to be used. What is the work done by the pump when 2000 liters have been served to the tank; what is the power of a pump selected to do this work in 20 minutes.

a very tall tree has tender buds up top, water enters through the root and is pumped, but where does the energy come from? a Hyperion, measuring at 379.3 feet (115.6 m), pumps to the top 50 liters of water in one day and this is a work of 56.7 KJ or watt*sec.

with 2012 hysteria and all, with who? with whom? and with who then? only one person? no make it two, the more the harder to choose you know. I already picked mom and doggy.

in the four weeks of dec 2011. seven thousand gallons of paint were sold and yesterday a total of 123 gallons were sent back by the distributor as "spoiled", 113 of them were checked as emulsifier error and 10 as color failure. The production can be grouped by colors as follows: 1345 yellow; 2746 blue; 2332 red and 577 white. a) What is the probability that a gallon of white paint be spoiled.

b)And if a blue gallon is spoiled, what is the probability it is by emulsifier error.

I left some riped bananas in the drawer with some green apples and these also riped fast, how can this be?

does anyone has details of how it works, I know that you supply compressed air and that´s the energy for both fluids to be pumped, but it´s a simple tube with a side entry for air and a centered output for air and water. I know it has to be a valve arrangement, I need serious help

the trees have the same age and are all of the same variety, I know that 12 oranges give me a gallon of juice, well sometimes I get the gallon with 11 oranges and the other day it took me 13 oranges.

I sold 360 oranges to these boy-scouts so they would make money selling juice, I talked to their Rover and he said the kids got to sell 36 gallons. Now I wonder, what is the probability they diluted with water?

I visualize the CO2/H2O mixture heated by the positive entalpy change, and the internal energy change liberated by the positive entropy change with the more number of gas molecules formed.

I wonder if it isn´t just the heat over the new number of gas moles that prevails.

use your own words and reasoning, maybe integrals?

the only fact is that the relation between the perimeter and the diameter of a circle is pi by definition.

the area inside this circle is pi*r^2.

i had the experience with this friend of mine, a scientist, disqualifying me for being a believer, so i did something very wrong i tempted him with $500 over his signing this document i made (i´m so sorry id did this) giving to me his soul for me to give to you know who and you know when, all he had to was sign i did not ask for a bit of blood....well he could not take the money he had in front of him on the desk. Anyhow, is there a real atheist? do you think so?

please balance the reaction

as a way of cleaning the atmosphere of CO2, is pumping it into the sea an option? will it be fixed in any way or will it just escape back?

besides water that is, What other organic product accompanies ethylene and what product is that with methanol dehydration

take this as a random sample of three cans over a 1000 cans lot
