What is the pressure difference between space and the surface of the earth?
The surface pressure of the earth is nominally 1013.25 hectoPascals (hP), which is also referred to as 1 ATM (1 atmosphere). The surface pressure of the earth will vary slightly according to weather conditions.
What device or instrument is used to measure air pressure?
If you're asking about a tool to measure the air pressure in a car tire, that is called a pressure guage.If you're asking about a scientific instrument to measure atmospheric air pressure, it is called a barometer.
Why might a sidewalk be built with periodic breaks in it?
As the weather changes the concrete expanse and contracts. The joints aka cracks act as a breaking point if the concretes put under to much pressure.
What causes sudden low water pressure you an entire house?
If you are on city water, a large pipe has burst somewhere causing pressure to drop drastically. If you are on a well, a problem has occurred in your pump, or your pressure tank, or the main pipe between well and house. In extremely cold weather pipes from a well can burst. Many well heads (at least in my area) are very inadequately protected.
What does bar pressure stand for and psi?
In the SI system the pressure unit is the Pascal (after the French maths genius) which is defined as 1 Newton per square meter. This is a very small unit. Atmospheric pressure is about 105 Pascals, and this is called the Bar. You have probably seen in weather forecasts the pressure given in millibars, the normal atmospheric pressure is 1000 mb, and the equal pressure contours on the weather maps give the millibar figure. These contours are called Isobars, as they are lines of constant pressure.Psi stands for pounds per square inch, which is I imagine easier to grasp, and is probably more widely used in the US. In Europe and the UK, in power plants and other industries, the pascal - kilopascal - bar units are used. I was brought up on psi and had to convert mid life, I have got used to bars but find kilopascals don't come easily.It is useful to remember that 1 bar = 14.5 psi. You will also come across psig, which just means pressure aboveatmospheric, it stands for psi gauge, as a gauge normally reads zero at atmospheric pressure. If you see psia, this means psi absolute, the pressure above vacuum, where atmospheric pressure = 14.5 psia.
How does the working system of a car ac affected by increasing the size of the condenser?
Increasing the size of the condenser, would help the system be cooler in very hot weather. Usually the condenser in the vehicle is as big as can be fitted.
How does a storm glass work to predict the weather?
A storm glass works by responding to changes in atmospheric pressure and temperature. When the weather is about to change, the liquid inside the glass will react by forming crystals or becoming cloudy, indicating potential weather changes.
How can pressure help us predict weather?
Low pressure usually bring lousy weather. A barometer measures atmospheric pressure. High pressure is associated with good weather low pressure with bad weather
How are pressure measurements related to weather prediction?
Decreasing pressure indicates stormy weather. Increasing Pressure indicates better weather.
How are wolverines becoming extinct?
Wolverines are becoming extinct because of the weather. The weather is getting warmer in Alaska wolverines can not live with out the winter.
Barometer are used to predict weather because weather is related to changing what?
The weather changes in relation to the air pressure. Air molecules always travel towards low pressure where there is less force acting on them. This has an effect on the weather. Generally, high pressure means good weather and low pressure means bad weather. Barometers measure the pressure, often in Hectopascals.
What is low pressure weather?
low pressure weather is cold fronts that move NW.
Why does the dodge 1500 pickup's condenser fan run in cold weather?
If the defrost is on, the ac will be on, and the condsensor fan will be on.
If stormy weather is approaching the pressure tendency probably be?
Barometric pressure decrease indicates coming stormy weather, rain, wind, , heat. Barometric pressure rise indicates fair, dry, colder weather. Slow, regular and moderate fall in pressure indicates low pressure area is passing at a distance. Any marked change in weather unlikely. Sudden decrease, even if small, indicates a nearby disturbance; normally bringing wind, and short showers. Large pressure drop signals a coming storm in 5 to 6 hours. Large, slow and sustained decrease indicates a long period of poor weather. Coming weather will be more pronounced if pressure started rising before dropping. Sudden rise of pressure,when the pressure is about average or above average and the weather is fair, indicates approach of a low pressure cell, and the barometer will soon start to come down. Rapid rise when the pressure is low, announces a short period of fair weather. If pressure rise is large and prolonged, count on a many days of good weather ahead.
Is air pressure part of the weather?
Yes, air pressure is a key component of weather. High pressure typically brings clear skies and fair weather, while low pressure is associated with cloudy, rainy or stormy conditions. Changes in air pressure can indicate the approach of different weather systems.
How are pressure measuements related to weather predictions?
answers Decreasing pressure indicates a change in weather.
How do rabbits predict weather?
Rabbits don't predict the weather. They may exhibit certain behaviors such as seeking shelter or becoming more active before a storm, but this is likely due to their sensitivity to changes in barometric pressure rather than predicting the weather.
