Imagine you’re in a room that’s filling up with water quickly. There are no windows or doors. How do you get out?
Answers
Answer:
Since there are no door/ windows in room. So we can assume it to be air tight. If water is coming from somewhere inside the room. The air inside has no way to escape and the room begins to get pressurized. At one point the incoming water pressure will equalize the inside air pressure and water will stop coming inside. So keep on floating at the surface, until some support come. Logically correct ???.
Answer:
The air inside can no longer escape, and pressure starts to build up in the room. At some point, the incoming water pressure equalises the indoor air pressure, and the water stops entering. So keep floating on the surface until support comes.
More information on water pressure:
Pressure is the force that pushes water through pipes. Water pressure determines the flow of water from the faucet. The pressure at the faucet can depend on how high the service tank or water tower is above your home, or how much water is used by other customers. The elevation of your property can also affect your water pressure; properties at the top of a hill may have less pressure than properties at the bottom of a hill. After installing the water meter, you should not notice a difference in water pressure.
Low pressure can reduce water flow to a trickle and make it take a long time to fill the kettle or tank. Some modern heaters and showers will not work below a certain pressure level. Before installing this type of equipment, you should check with your water company to make sure that the pressure in the company's area is sufficient for these systems to operate effectively.
Low pressure can be caused by several factors. For example, when water demand is high (for example, in the morning or early evening), the pressure may be lower than during the rest of the day. Problems can also occur during dry periods when people use hoses or sprinklers to water their gardens.
