Air is a compressible fluid composed of (mostly) oxygen and nitrogen. If you compress air, then...
The air that we breathe is composed of 78% nitrogen (N2), 21% oxygen (O2), and the other 1% includes water vapor, carbon dioxide, and pollutants. If a tire is inflated to a pressure of 33 pounds per square inch (psi) with regular air, what is the partial pressure of nitrogen and of oxygen within the tire?
Q6 (a) Explain briefly the different between incompressible and compressible fluid flow (5 marks) (6) Air at pressure and temperature of 200 kPa, 373.2 K flows through a duct at Mach Number of 0.8. The gas constant and specific heat ratio of air are 0.287 kJ/kg k, 1.4 respectively. Determine, (1) air velocity: (11) stagnation pressure: (111) stagnation temperature and (iv) stagnation density (8 marks) Nitrogen enters a converging diverging nozzle from a reservoir at a pressure of 700 kPa...
Ideal Fluid - The Ocean. Water is much less compressible than air. This means that the density of water (~1gm/cm3 or 1000 kg/m3) does not change very much with increasing pressure. This means that as you go deeper in the ocean the mass of water above you is just proportional to depth that you descend. Assuming that you can neglect the small change in gravitational acceleration with depth, show (so that a non-science major friend could follow - do not...
1. In a room full of air, the air is mainly composed of Nitrogen and Oxygen molecules (both at room temperature). Find (to two significant figures) the values of Vrms for both molecules. (Eq.

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...

A compressible fluid has density ρ = 1000 kg/m3 + h × 20 kg/m4 , with h the depth of the fluid. What is the pressure difference between a point at the surface and a point 2 m below the surface?
Air a. What is the volume of air in the room where you are right now? (You can measure the length, width, and height of the room with a measuring tape, or you can estimate these quantities. Just make sure you convert your answer to SI units.) b. What is the temperature in this room? (in SI units) c. Look up the current barometric pressure in your area, and convert it to SI units. d. Use the information from steps...
