According to Mythbusters, 60 ml per hour.
You sneeze more when you have a cold because the lining of your nose is very inflamed, and your nasal passages are full of mucus. Very often, this mucus, or something caught in it, irritates your already inflamed nose, and makes you feel a tickle. This causes you to sneeze forcefully, helping to clear the excess mucus from your nose.
to get rid of the mucus and germs in your body.
Mucus membranes trap dirt, viruses, and bacteria and keep them from entering the body. However, many people produce too much mucus when they have a cold or allergies. This causes a stuffy or runny nose.
Ways to deal with the common cold would consist of getting a lot of rest, staying hydrated, and trying to eliminate as much mucus from the body as possible. Steam baths and hot showers will help loosen mucus. Consistent blowing of your nose will help remove the mucus.
If your nose is "running," then you have a mucus discharge. The image is of the mucus running out of your nose so that you need a tissue or you need to blow the mucus out.
You possibly have a cold.. It could suggest something else but a cold comes to mind first
The nose is a complex organ, meant not only to help us smell wonderful (or not so wonderful) smells but also to act as a filtration device for incoming air. It might be surprising to learn that your nose secretes, when you're healthy about 32 ounces (.94 liters) of mucus every day. This doesn't tend to make your nose run; instead most of this mucus falls to the back of the throat and is eventually swallowed. These secretions help to humidify, warm up, and filter incoming air, in conjunction with the small hairs in the nose. So why does a nose run when it is cold? This is an excellent question, which fortunately has a fairly simple explanation. Underneath the glands that secrete mucus, you have huge amounts of tiny blood vessels, which help supply these glands. In cold weather, these blood vessels dilate or grow larger. This means you have more blood supply to your nose, which in part protects your nose from the cold, but it also means your nose will begin producing greater amounts of mucus and liquid. This is also why your nose turns red when it's cold. Additionally, you will notice a nose run when it is cold because the nose has to work overtime to warm up air that is inhaled, which is coming in at much lower temperatures than normal. You might even notice a nose run when it is cold only by a few degrees. Temperatures just a few degrees below room temperature can make the nose run. There's also the issue as mentioned above of normal mucus and secretion production. At room temperature, your nose is already producing four cups of fluid and mucus a day. Only so much of it can fall to the back of the throat and be swallowed. When mucus and secretion production increases to warm the air, you will see the nose run when it is cold because you have excess secretions. In other words, some of it has to drip out the front of the nose because you have an excess supply. When you get into a warmer room, a few moments later you won't notice your nose continuing to run because your nose has warmed up and the blood vessels become more constricted. Observing the nose run when it is cold has led many to believe that cold weather causes colds. This isn't actually the case, and the nose helps through filtration to try to avoid viruses. Of course it doesn't avoid them all. Being out in cold weather for a few minutes may actually help decrease congestion a little since mucus will be naturally released through the front of your nose, allowing you to have a few good blows. Usually, you're just as stuffed up again once you've gone back indoors.

Because your nose is clogged, so particles used by the nose to detect smell are no receiving the particles because mucus is blocking the way.
Well it is when you get a tissue to eliminate the mucus from your nose. You blow and the mucus that is stuck in your nostrils will come out!
Mucus.
The cat might be congested or have a cold, flu or disease of some sort.
