Why does groundwater depletion cause longer-term problems than might result from the draining of a surface reservoir?

So in this problem we will be discussing about the components of domestic see wage, but before that we shall just give an idea of what to see wage to see which is the wastewater that is produced from community, from community of people and domestic see wage. Domestic see wage is the used water that are coming from houses and apartments, mostly from bathrooms, laundry and kitchen and what are the components of domestics image? Domestic savages composed of suspended particles includes the soil particles such as sand and so there are colloidal particles. Colloidal particles are organic mineral materials and inorganic materials such as fecal matter. People not and bacteria. The next component are dissolved solids in this includes nutrients, moody um calcium, ammonia nitrates and who stayed the last component of the domestic see wager pathogens, disease causing organisms. There are various pathogens that were found in their domestic sea region, including the tattoo regions for cholera, diarrhea, the sentence entry, um typhoid. So what is the impact of CV discharged on rivers and see which is discharged into the reverse? It causes degradation of the river water through various some processes such as eutrophication. It causes growth of pathogenic bacteria because domestic see, which contained pathogen to those pathogenic organisms are transferred to the river water and their growth is and how they're it also calls aging of the world water how it causes aging of the river water. It is because of the accumulation of the the silk and the game matter. In the reverse, we start to fill up the reverse. The biological oxygen demand of the river is increased due to disposal of domestic See wage in river water. The there is destruction of naturally little flora and fauna of dirty work when domestic thing really is disposed into the water. So this is the effect of civil discharging to divorce.

This question. He wants to explain. Why is it that the sink drains has this, uh, particular set up key? So it looks something that this Yes, sir. So the sink drain has this set up. So, um, my answer. So this devise, uh, 10. Reduce the chains for have you lens to form in the think Because if turbulence occurs, uh, speed off water reduces he. So if you look at the formula for Reno's number, which is to roll, we are You're Aida. So this device reduces that are in that formula key. So if that is known, your death. Yeah. This shader pious accent the are will be greater than when you installed the device with this, uh, plus thing in between. Okay, so yeah.

In the given problem we will be discussing about the series. So what is seaweed? See wages the wastewater containing human excreta. There is a very the sea rich contains already high amount of biodegradable organic matter, as well as my group that might be pathogenic in nature. So when the sea wages dumped into the water bodies causes pollution on those water bodies and make the water and fit for human consumption, it is one of the cause of various waterborne diseases, including diarrhea, call it uh, essentially, and they breed. So what happens is when the seals, when the sea, which is dumped into water bodies, it is decomposed by their naturally occurring microbes in presence of oxygen in the water. This causes a sharp decline of God, dissolved oxygen or water of the water body. So when the dissolved of vision is declined, the aquatic animals will get suffocated. And if such water is consumed by humans, it will cause various Various water one disease. So this is why steve which is harmful for humans.

This problem way Have a full of water, a some velocity coming out of a hose here, as I've kind of drawn a schematic and your washing a car. And it's some pressure here that's obviously created back here to expel this water out at some velocity. Eso We also have some velocity here, and I'm gonna use a little V with line through it. A civil Aasif e s. So it's not confused with volume. And I can't draw boldface feel like they do in the book. So we have the water coming out here. Is that some height about ground here? So it hits the car and obviously the velocity is going to drop. Um, won't drop to zero because obviously it will splash off, but eventually it will. It will drop some, and it will obviously change its direction So the kinetic energy will go down. Which means that the if the if we assume that on average it's still at the same height. The potential energy hasn't changed. So the internal energy must change, so that will increase the temperature. And that will also caused the entropy. Um, go up. Um, so that's also let's see here, It obviously is not gonna change much. And obviously you also have to be considered. You know, if the water isn't at the temperature of the surroundings, there's gonna be heat transfer. I'm assuming it's probably usually be colder than the surrounding. So there's gonna be some heat, you know, it's gonna be warming up. So, you know, you gotta There's a lot of assumptions here, and they were Just assume that the temperature is at the surrounding the water. Is that the surrounding temperature? So after it hits the car, then falls to the ground, which means that the potential energy goes down and likewise, the entropy is going to go up. And, well, I guess it depends on how warm the water was. So it could be Either the water is going, you know, up or down, the temperature is going up or down, as it kind of equal a break with the surroundings. Um, so we have the temperature go slightly up again, assuming it was at the surrounding temperature when it was here. So it falls down, the temperature goes up slightly and the entropy goes up slightly. Now, if the temp, if it was um, at ambient temperature here and then a temperature went up slightly here. Then it's gonna have to decrease here and again. We'll get an increase in entropy as that is transferred. Um, let's see here. That's pretty much it again. There's a lot of assumptions here. Um, but generally speaking, we have kinetic energy here, and potential energy, potential energy and kinetic energy go to zero here, at least if we're using this as the reference or they dropped. So that means the internal energy has to go up, which means that heat is going up on that and also the entropy will be going up. So let's see. Is president also put Yeah. So again, these are irreversible processes, so we haven't increases in entropy. Obviously, the entropy in the water actually could go down here, but obviously the net entropy of the water and the surroundings will necessarily increase
