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, ..
The selection of the factor of safety to be used for various applications is one of the most important engineering tasks. On the one hand, if a factor of safety ..
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 ..
An automobile is a vehicle that is capable of propelling itself. Since the 17th century, several attempts have been made to design and construct a practically operative ..
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 ..
High-Speed Steels (HSS) are the cutting tool materials used for machining of materials. The HSS will be used for machining of materials. The General use of HSS is 18-4-1. ..
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 ..
In a sliding joint, contact force always acts perpendicular to the surface in contact. This contact force is commonly referred to as a normal force because it acts ..
