It makes no difference. Density = mass / volume. You divide the mass by the volume. If the volume is greater than the mass your answer will necessarilybe less than one, but that is still the correct answer showing the density in terms of the units used. 12-6-2014В В· The conservation of mass specifies that the mass flow rate through a nozzle is a constant. If no heat is added, and there are no pressure losses in the nozzle, the total pressure and temperature are also constant.

Learn the definition of pressure as the term is used in chemistry, physics, and engineering, a look at units, and how to calculate pressure. The key difference between low and high pressure systems is that low pressure systems are regions in the atmosphere where the air is rising, The word pressure system is a common term in meteorological reports, decreases. As a result, the water in the air mass vaporizes, creating dry weather conditions.

If the initial air was at atmospheric pressure, the pressure will rise by one atmosphere (14.696 psi, or 101,325 Pa). If we assume a pump diameter of 1.25 inch, then a force of 18.1 lbf will be required. This is not a large force, so that raising the pressure by two atmospheres above ambient pressure is easily done.

When you deal with the pressure of a liquid at rest, the medium is treated as a continuous distribution of matter. But when you deal with a gas pressure, it must be approached as an average pressure from molecular collisions with the walls. Pressure in a fluid can be seen to be a measure of energy per unit volume by means of the definition of work.
