There is a difference between pressure and flow in hydraulics such as water. If your source is a water tower, like city water, the pressure is constant, or static, however flow depends upon pipe size and other factors. For example, you may be dissatisfied with the flow of your shower but you look out the window to see a truck crash into a fire hydrant. "No fair!", you cry as you envy the neighborhood children getting a more satisfactory bath than you just had, with apologies to the truck driver abused in this example though he also got a better shower. That is, the six inch diameter fire hydrant main line produces considerably more flow than the 3/4 inch line to your house, especially if someone flushes and robs your flow. To specifically address well water pressure concerns, you have to understand that your pressure is artificially created. You rely on a pump for that purpose. As you investigate potential problems with your pump keep in mind that pressure is not the same thing as flow. See the links. BTW: As a concrete guy, I have a personal interest in hydraulic pressure because it has a direct impact upon my preparation of formwork to contain liquid concrete in its desired place until it hardens. The physics are the same as water, but engineers use a caveat in these pressure calculations which defy common sense. The constant of pressure exerted by height (gravity) is not allowing for friction. "Discounting friction" is how they put it. That is, consider the amount of piping in your home. Okay, now consider the same amount for your neighbors and then image how many others share the same source of water, maybe a million people. Now consider the loss by friction, the rubbing of water molecules against all manner and size of piping, before you can turn on the spigot. Friction loss is huge in hydraulics. I have met men who have formed and poured concrete all their lives who call me crazy when I tell them that a one foot wide concrete wall form has the same pressure at the bottom as a three feet wide form, if the height of the wall is the same. Technically they are wrong, but their experience tells them better. "Discounting friction" in pressure calculations is like getting robbed, discounting the threat.

They mean different things. "When" = "at the time that." "While" = "during the time that." Did you lose weight when you were running every day? You must carry water with you when you are running long distances. I have a chance to enjoy the scenery along the trail while I am running on the hiking path. It is hard to carry on a conversation while you are running.

Put simply, a correctly designed and fitted system does not lose pressure.I would guess that there is a pinch point somewhere in your system. This allows the pressure to get up to normal when the system is a rest, only to reduce as the water further up the pipe cannot get through the pinch point.Possibly there are too many bends in the system, each bend reduces the water flow.If you lose pressure /volume while a faucet is running the cause could be mineral deposits inside the piping. The trouble could be at the hot water tank as many installers forget to install a dieelectric fitting such as a nipple or union

You must have a leak somewhere. If you are on a well check the pressure tank, make sure there is adequate air pressure. ( check at nipple on top, should be in excess of 25 psi) Check the pipe to well. Listen carefully at the well while pump is running. If there is a leak in the down pipe or lower check valve you will hear water hissing. If none of these ideas work, post again and be more specific about your system.

Through respiration and perspiration.

Water replaces the sweat you lose though sweating.

The water loss is due to sweating to cool the body.

Running raises our metabolic rate, so we burn calories even while at rest. Running helps to burn calories while watching TV, while sleeping, even while taking a shower.

When flowers lose their turgor pressure, or dry out they become wilted. If you remember to water them, flowers have abundant turgor pressure, and they will stay stiff, but if they become dry, or you forget to water them, they will lose their turgor pressure and begin to wilt.

Both running and swimming are great ways to lose weight. Running tends to be easier to achieve because you can do it anywhere. Swimming has added benefits of water resistance which can help tone muscles while burning calories.

Cinderella lost a glass slipper while running from the ball at midnight.

yes it does help you lose weight because water has hydrogen in it and h20.

All pipes in a house are connected, so when two outlets are turned on the water has to change from going in one direction to being divided and go two directions. However, the loss in water pressure should only be temporary . . . usually the system will re-adjust

Running in water presents your body with more resistance than running on dry land (in air) and so makes it a great exercise which is also a lot gentler on the joints than running .

The amount of weight you lose while running depends on the distance you travel. For an average person, in a mile, they lose 100 calories. For more information to answer anymore of your questions be sure to go through this website:

yes, there are few better ways to lose weight than cardio and hydration.

There is a screen and/or a water saver in the shower head. The screen may be plugged with sediment from in the water.

It purely depends on how far you are running and how often. There is the potential to lose a lot of weight if running remains a constant factor in your life. Just to give you an example, the average person burns 700 calories and hour while running.

do curl ups and pushups while walk some times

Running is the best way to lose weight but not the fastest way. Keep running.

If someone were to flush a toilet, the water pressure could drop accordingly. If you lost all water pressure, chances are that your main water line coming into the home has a huge leak or not enough pressure. The hot water tank is pressurized by the cold water pressure coming into the house. If there is no water flowing from the water meter into the home, you won't have any hot water either.

If you have a leak on the hot water somewhere in the house and the water input into the tank is not running, the tank will lose it's water. And if it is an electric tank, the elements will burn out. Gas hot water tank should be no problem. Pressure valve does not have to be open.
