Several welding processes are available; however, their application is dictated by the mechanical properties, type of welded joints, the quality required in the service condition, cost, and availability of the machine and operator’s skill.   The discussion below gives …

Any body with at least one measurable property that changes as temperature changes can be used as a thermometer. Such a feature is called a thermometric property. The particular substance that exhibits variations in the thermometric property is known as a thermometric …

The sources of air in the condenser are due to the following: Leakage through packing glands and joints. Leakage through condenser accessories, such as the atmospheric relief valve, etc. Air associated with exhaust steam may also be liberated at low pre…

The metalworking fluids applied in machining processes basically have three characteristics. They are: Cooling effect Lubrication effect Taking away the formed chip from the cutting zone. Selecting a metalworking fluid for a particular application and…

Steam condenser is an equipment in which the exhaust steam from the steam turbine is condensed by means of coolant (water). Thermal efficiency of a closed cycle power developing system using steam as working fluid and working on carnot thermodynamic cycle is given by …

The below table can be read like the table of comparison between the two types of engines and also as the merits and demerits of the two designs. 4-Stroke and a 2-Stroke Engine comparison S.no 4-Stroke Engine 2-Stroke Engine 1 One working stroke for ev…

In jet condensers, the exhaust steam and cooling water come in direct contact with each other, whereas in surface condensers they don’t mix with each other. The temperature of the cooling water and the condensate is the same in jet condensers when leaving the condens…
