China Launches Most Powerful Rocket Yet For Deep Space Exploration

China launched it’s most powerful rocket yet on May 5 2020 into orbit carrying it’s next generation space capsule to test it’s ability to carry astronauts and it’s overall performance while in space. The purpose of the launch is to verify the rocket’s workability and it’s reliability to carry astronauts and supplies to a future…

Laser

A laser is a device that emits light through a process of optimal amplification based on the simulated emission of electromagnetic radiation. The term “Laser” comes from the acronym for ” Light Amplification by Simulated Emission of Radiation. Laser differs from other sources of light because it emits light which is coherent. This coherence enables…

3D Printing

3D printing involves building a three dimensional object from a computer aided design model by successively adding materials layer by layer on top of each other using a 3D printing machine. Within the last decade 3D printing usage has increased dramatically that this technique is now used for industrial applications such as building apartments and…

Air Compressor

<a An air compressor is a device used to compress atmospheric air taken in through inlet valves and compressed to a high pressure, the compressed air being used for various purposes such as cleaning, spray painting, pneumatic operations, starting the main engine, etc. Air compressors force air into a tank, increasing its pressure. When the…

Sonar

<!– wp:paragraph Sonar or Sound Navigation Ranging is a technology which involves the use of sound to detect vessels and other objects underwater or on the surface to aid navigation and avoid collisions. Sonar are of two types: active sonar and passive sonar. Active sonar emits pulses of sounds and listen to echoes from other…

Incineration

Incineration is a waste treatment process that involves the burning of solid waste in an incinerator. The burning process produces ash, heat and flue gases. Incinerators are very effective in reducing the volume of waste used for landfills and very popular in countries where land is scarce. The waste is usually compressed before being delivered…

Refrigeration

Refrigeration is defined as the science of providing and maintaining temperature below that of atmospheric temperature. It means continuous extraction of heat from a body which is already below atmospheric temperature. Refrigeration involves cooling a space, substance or system to lower its temperature or maintain that temperature below its ambient temperature. Energy in the form…

Stern Tubes

<a The stern tube is a hollow tube located at the lower stern part of the ship carrying the tail shaft and connecting it to the propeller,bearing for the tail shaft, lubrication arrangement and sealing arrangement. The propeller shaft or tail shaft is supported in a stern tube bearing. The bearing being at the end…

Deep Submergence Rescue Vehicles

<a A Deep Submergence Rescue Vehicle or DSRV is a marine vessel used for rescuing crew from downed submarines and other clandestine missions. These are specialized vessels that require highly skilled professionals to operate these vessels and successfully carry out complex rescue missions. There are a number of countries that operate DSRVs with different designations…

Heat Exchangers

Heat exchangers are devices used to transfer heat between two or more fluids. They are used for both heating and cooling processes. The fluids may be separated by a solid wall to prevent mixing or may be in direct contact. They are widely used in refrigeration, chemical/ petrochemical processing plants, power stations, refineries and sewage…
