OIL AND WEAR PARTICLE ANLYSIS Abstract: Oil and wear particle analysis is a very powerful tool used to monitor and assess the health of a machine. Since the lubricant in a machine passes through all the internal parts that can wear‚ it is vital to maintain the quality of the lubricant thought oil analysis. Furthermore the presence of wear particles that are deposited in the oil can give a good indication of the wear material and the possible location of the abnormal wear

A molecule of water consists of one oxygen and two hydrogen atoms joined by covalent bonds. Water as a liquid is vital to existence and plays extremely important roles in many aspects of both plant and animal lives. These aspects include temperature control‚ support‚ chemical reactions‚ transport and protection. Without the ability to control our temperature‚ we as humans would not be able to survive in our natural environment. If our internal body temperature was to rise or fall even a few degrees
