Preventing Water Hammer from Damaging Pumps and Pipes

Water hammer occurs when the flowrate of fluid in the pipe changes rapidly. It is also known as "surge flow". It can cause very high pressures in pipes, very high forces on pipe supports, and even sudden reversals of flow. It can cause burst pipes, damaged supports and pipe racks, and leakage at joints. Water hammer can occur for any fluid ...

What Happens When you Touch Nitrogen? | Physics Van

Ordinary nitrogen at room temperature is a gas that makes up 78% of the air we breath. If you would touch liquid nitrogen very briefly (I advise that you don't do this) you would certainly feel cold. If you stuck you finger into a flask of it for some time the liquid nitrogen would boil furiously and then your finger would freeze solid.

The Details: Nitrogen is a gas in the air. In fact, air is about 78% nitrogen. Air is also made up of oxygen, carbon dioxide, hydrogen, water vapor, and many other gases in small amounts. When a gas is made very cold, it turns into a liquid similar to water. Liquid nitrogen is just very cold nitrogen. It is 320 o F below zero (-196 o C).

3 Liquid Nitrogen Experiments You Can Do at Home

Liquid Nitrogen Science. As the name implies, liquid nitrogen is nitrogen in liquid form. Nitrogen (in the form of N2) makes up most of the air we breath. It dissolves into our tissues; it is absorbed by plants; and is an essential element in the building blocks of our DNA. Most of the time it exists as N2. Ammonia and Ammonium are other common ...
