The sources of air in the condenser are due to the following: Leakage through packing glands and joints. Leakage through condenser accessories, such as atmospheric ..
In surface condensers there is no direct contact between the steam, cooling water and the condensate can be reused in the boiler: In such condenser even impure water ..
Basic Weld Symbols The basic weld symbols according to IS: 813 – 1961 (reaffirmed 1991) are shown below with sectional representation and symbol in the tabular ..
Shielded Metal-arc Welding (SMAW) is the simplest and used for many joining processes. More than 50% of industrial and maintenance welding currently is performed ..
Gas Laws explain the behavior of an ideal gas in terms of temperature, pressure, volume. The following are the some of the important gas laws: Boyle’s Law Charles ..
The LMTD is a logarithmic average of the temperature difference between the hot and cold fluid streams at each end of the heat exchanger. The larger the value of LMTD, ..
Structural failure can be avoided if the loads that a structure is capable of supporting are greater than the loads it will be subjected to when in service. Since ..
The smallest unit of material, atom, consists of three particles. They are Electron, Proton, and Neutron. Electrons are negatively charged particles of magnitude ..
Pascal’s law states that A small force (F1) is applied to piston with a small area (A1) produces a much large force F2 on the larger piston. It is schematically ..
Many hygroscopic (moisture absorbing) materials can be used as relative-humidity sensors. Such materials absorb or lose moisture until a balance is reached with ..
A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation ..
Merits of Water Tube Boiler over Fire Tube Boiler: Generation of steam is much quicker due to the small ratio of water content to steam content. This also helps ..
The process of welding and cutting of metals involve the application of high heat energy to the objects being welded or cut. This high amount of heat energy for welding ..
A dynamometer is a device used for measuring the torque and brake power required to operate a driven machine. Dynamometers can be broadly classified into ..
