Gas Tungsten Arc Welding (GTAW) or Tungsten Inert Gas (TIG) Welding

Gas tungsten arc welding  or GTAW  is the same as tungsten inert gas  or TIG  welding. It  is also an arc welding process. Here a non-consumable electrode is used. And most importantly - the electrode is made of  tungsten. And this electrode helps to produce the weld. The weld area is protected from atmospheric contamination or oxidation by usually an inert gas. This shielding gas is generally

CAT Engine Course(Part 4) Cooling System

Cooling System COOLING SYSTEM SCHEMATIC This diagram shows the basic cooling system. We can use it to see the components of the system and see how they are connected. In the diagram, we see the engine block, cylinder heads (separate heads for each cylinder), coolant manifold, housing of the temperature regulators (thermostats), water outlets bypass line from regulator housing to water pump, water pump, water inlet from radiator or heat exchanger, coolant line to the aftercooler, and the oil cooler. 1. water pump 2. oil cooler 3. cylinder heads 4. water manifold (right side) 5. aftercooler 6. temperature regulator housing 7. bypass line from regulator housing to water pump. COOLING SYSTEM FLOW Coolant flow comes from the elbow which is connected to the radiator or other heat exchanger into the center of the water pump. The cooler flow is divided at the outlet of the water pump. One partflows to the aftercooler; the other part to the oil cooler. Coolant sent to the aftercooler goes throu...

Log Mean Temperature Difference (LMTD) Method with Examples

Logarithmic Mean temperature Difference is used to measure the Heat transfer rate in double pipe heat exchanger. The rate of heat transfer is got from the formula - Q = U.A.LMTD . U= Heat Transfer Co-efficient A= Heat Transfer Surface Area LMTD=  Mean Temperature Difference LMTD is the logarithmic temperature difference between the hot and cold fluids passing through the each ends of heat
