Will adding another water heater boost the water pressure in the house in addition to giving more hot water?
No and yes. No, you won't get more water pressure. To do that you'll need to find out why the water pressure is low. Perhaps flow restriction, perhaps a poorly adjusted water pressure regulator, perhaps low pressure from the well/city water. But an additional water heater will certainly give you more hot water. It would be like putting in a LARGER water heater. In most cities the water pressure required is about 20 PSI. Small city's do not add pressure pumps to their system but use a gravity supply. That is why most places there is a pressure problem either build their water tanks taller or erect them on a hill.
Can you have too much water pressure in a residential house requiring a pressure release valve?
The water pressure in my house is about 140PSI. Which is definitely dangerous. It happens more often than you would think. What happens is a city will use water supply lines which are too small for the water requirements. Therefore, they have to increase the pressure. You wouldn't want a pressure relief valve, because then if the pressure was too high, it would just spray water everywhere to release the pressure. You would want a pressure regulator installed, which is what I am working on for my house right now. Just to let you know though, you may have to get a thermal expansion tank for your water heater if you don't have one. See, the new pressure regulators have a check valve in them, which prevents water from traveling back into the city pipes once it has gotten into your house. When your water heater heats the water, the air bubbles in it expand, which increases the water pressure, and will probably cause your pressure relief valve on your water heater to blow. You can get a cheap water pressure meter at any improvement store to check it out. 50-60 PSI is ok. I would say you could take it up to 70 or 80 PSI safely.
What is a normal operating pressure of a fire hydrant at the nozzle when operational?
It varies. I have seen a range of between 50 psi to 225 psi. It is affected by distance, size of water lines and their configuration and elevation change from source to the hydrant, as well as the type of pressurization, gravity or pump. On average though 80 to 100 psi. Of course a larger nozzle would decrease the residual pressure while a smaller nozzle would tend to increase residual pressure. 125 psi is about the maximum pressure for a "hand line" in order to be manageable.
Water flows at 12ms in a horizontal pipe with a pressure of 30000 Nm2 If the pipe widens to twice its horiginal radius what is the pressure in the water section?
the answer would be 48 m/s
What would make the water pressure in a house go above 80 psi?
Area water authority could have increased water main pressure, no or defective expansion tank in house main water line if house has a backflow preventer installed, or defective /not properly set pressure reducing valve.
Does gravity affect density's properties For example if there was no gravity would objects that typically sink in water not?
Gravity may cause the density of a medium to vary with depth. For example because we have gravity the pressure in water is much higher 1 kilometer below the surface than just 1 meter. This is because the water at 1 kilometer down also has to carry the water above it. If there was no gravity water would not fall down, and as such there would be no pressure (and thus no density difference). Without gravity objects would not sink. Think of it this way; the only thing that separates up from down in water is that gravity pulls things down. If it was not present up and down would be equal, so you expect the object to respect that and just remain where it is. By the way, liquid only varies very slightly with increased pressure.
What can upset the balance between gravity and pressure in a nebular?
You used the term nebular. I take it you mean a galaxy. There would not be a balance between gravity and pressure. There would be a balance between gravity and centrifugal force.
Would a Human Being Face Neptune?
Neptune's "surface gravity" is a bit more than Earth's, but Neptune's gravity would not crush you. If you went deep inside Neptune the pressure would probably crush you. That's not gravity crushing you directly, but the pressure. This pressure is caused by the combination of gravity and the planet's resistance to being compressed by gravity. The pressure increases rapidly with depth.
What would happen if the pressure exceeded gravity?
we would all die
Why water tanks in tall buildings are placed at the top of the buildings?
To allow gravity to provide the pressure in the system. The alternative would be for powerful pumps to be used and that would be an expense
Would a can of coke be crushed due to gravity or atmosphereic pressure in venus?
I think it can because there is a lot of atmospheric pressure so it can be crushed at one point.It would be crushed very quickly. The pressure on Venus is almost 100 times the pressure on earth. The gravity on Venus is less than the gravity on earth, however.
Why does air pressure happen?
Air pressure is a product of the operation of gravity on the mass of atmospheric air. If there were insufficient or no gravity on Earth, the atmosphere would drift off into space. There would be no air pressure. But, because there IS gravity on Earth, the atmosphere presses down on Earth's surface, resulting in the phenomenon known as air pressure.
Why does the water tank is placed at high places?
Gravity. The tower is placed high so that gravity will create pressure and force water through pipes without any mechanical assistance.To give the water potential energy. The water can flow down hill without using pumps.It creats water pressure. Water flows from a higher place to lower place without a pump using only gravity. Once the water levels are the same you'd need a pump to transfer the remainder of H2O. The higher the start the faster the flow ( until you reach the force of gravity) and thus the better pressure coming to your home and faster the shampoo is rinsed out of your hair.
Would gravity on venus squash a human?
No. The gravity would not crush a human. The pressure from the atmosphere would.
Would you feel more pressure 5 m underwater in a pool or 2 m underwater in the lake?
Under 5 m of water the pressure will be greater than under 2 m of water. The shape of the body of water is irrelevant.
What is the pressure at the bottom of the ocean?
The pressure at the bottom of the ocean can be determined by the formula P = dgh, where d = 1025 kg per cubic meter, g is the acceleration due to gravity and h is the depth of the water in meters. At the bottom of the Marianas Trench (11034 meters), the pressure would be 1.11 E5 kPa, or 1095 times normal air pressure at sea level.
On a distant planet the acceleration due to gravity is less than it is on earth Would you float more easily in water on this planet than on earth?
Both your weight and the water pressure would decrease, so it would be the same as on earth. Floating is nothing to do with the size of g, provided it isn't zero, or water pressure. If your density is less than that of water, you will float.
