While gynecomastia is the most common breast abnormality in men, other benign tumors that are common in women, such as fibroadenomas and papillomas, occur in men in rare occasions. According to the National Cancer Institute, the types of breast cancer most commonly diagnosed in men are similar to those found in women.
The compressibility factor (Z), also known as the compression factor, is the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.It is a useful thermodynamic property for modifying the ideal gas law to account for the real gas behavior.igure 2 is an example of a generalized compressibility factor graph derived from hundreds of experimental PVT data points of 10 pure gases, namely methane, ethane, ethylene, propane, n-butane, i-pentane, n-hexane, nitrogen, carbon dioxide and steam.
The C-Factor is a measure of the smoothness of a pipe's interior. All pipes have a roughness that resists water flow and causes a drop in pressure under flowing conditions. The roughness is indicated by a factor we call the C-Factor. The higher the C-Factor, the smoother the inside of the pipe. New plastic pipe would have a very high C-Factor. Old steel pipe would have a much lower C-Factor because of the corrosion that may have occurred within the pipe.
