    Dot 3 Brake Fluid

    Dot 3 brake fluid is an oily fluid used in hydraulic brakes to transmit pressure from the brake pedals to the brakes. Brake fluid is very hazardous and should be handled and stored properly. The chemical name is glycol ether blend. Brake fluid has a mild odor and is not flammable. It can cause severe irritation to the eyes and skin. If consumed in the eye brake fluid can cause damage to the cornea. This fluid contains 2% ethylene glycol which can be toxic if ingested. Ingestion will affect the central nervous system, lungs, and kidneys. Inhalation may cause respiratory irritation. If fluid comes in contact with eyes then flush with water for 15 minutes. If contact with skin wash with soap and water thoroughly. If inhaled remove to fresh air if breathing is affected seek medical attention.…

    Hydraulic Jump

    In this paper, the group proposes an analytical representation for the occurrence of hydraulic jump flow. The experiment showed that hydraulic jumps happen when a high velocity liquid enters a zone of lower velocity. The approach used by the group is controlled volume method, as it is the most commonly used approach in analyzing hydraulic jumps. Using the Reynolds Transport Theorem and with the aid of some very helpful assumptions, the group found a relationship between the characteristics of the jump upstream and jump downstream, as well as the entrainment. Unfortunately, the figures that were observed experimentally were not close enough to theoretical values. But the group has seen the accuracy and performance of the experiment apparatuses – scales, sluice gate – will affect mainly the data that will be observed.…

    Hydraulic Systems in Aircrafts, and Their Operations and Functions

    Hydraulics is based on a very simple fact of nature - you cannot compress a liquid. You can compress a gas (think about putting more and more air into a tire, the more you put in, the higher the pressure). If you're really strong you can compress a solid mass as well. But no matter how much pressure you apply onto a liquid, it isn't possible to compress it. Now if you put that liquid into a sealed system and push on it at one end, that pressure is transmitted through the liquid to the other end of the system. The pressure is not diminished.…
