By cooling the compressed air between each stage, the compression curve moves to near isothermal. The work done by the compressor is less if it is multi-staged. Read here to learn about the multi-stage compressor and its advantages.
As the delivery pressure demand on a single-stage compressor increases, the quantity of compressed air delivered decreases. Find out how this happens and learn about the limitations of a single-stage reciprocating air compressor.
Air is freely available everywhere. But Compressed air is not. So what is compressed air and what happens to air when it is compressed. Read here to know about the thermodynamics and simple physics of compressing air. Also appreciate the reason for compressing air polytropically against isothermal.
In my last article, a brief history of Marine engineers and their nature of work on board a merchant ship. Let us now discuss the areas of specialization and specific duties and responsibilities of Marine engineers on board a merchant vessel.
Read here to know about a different branch of Engineering Studies, Marine Engineering. Also one will be shocked to know that Marine Engineers are the only one, who excel in every branch of engineering with both practical and theoretical knowledge. Read here to know the duties of marine engineers.
We all know that the hydraulic systems are used from simple tipper trucks to an aircraft. Read here to learn about the applications of hydraulics on board a ship. Know about the simple description of steering gears, stabilizers, valve actuation, bow thrusters, and other engine room applications.
Hydraulic systems are used from tipper trucks to aircraft rudders. Read here to know about the simple hydraulic components and circuits used on board a ship. Know about the working of the direction control valve and construction of reservoir with its safety arrangements.
We all know about the supply frequency which is essential for any electrical machinery. But can you run a motor rated for 50 Hz on a 60 Hz supply, or vice versa? Read here to know the in-depth analysis of the above conditions.
On 17th August 2009, some repair work in the engine and turbine room caused a sudden “pressure surge" in one of the water pipes and caused the pipe to burst out, letting huge quantities of water into the turbine and engine room. Twelve people died and 68 are missing.
Can you believe that you can measure the height of a tall tower or a building with the help of a friend and his/her height? Read this to learn how to measure the height of a tall tower using a clinometer, a friend, and simple physics formulas.
A tall building like the “Burj" in Dubai is almost 818 meters (2684 feet) above the ground level, which is currently the world’s tallest man-made structure. But how can you calculate it’s height? There are actually several methods of doing so without leaving the ground.
The hydraulic ram is a pump which raises water without any external power for its operation. One essential requirement for the satisfactory operation of ram pumps is the availability of large quantity of water with a small positive head or height. “Water Hammer” is the principle used in pumping.
An air-lift pump is a device which is used to lift water from a well or a sump with the use of compressed air. The compressed air is made to mix with the water. It is well known that the density of water is more than the density of air. This density difference helps to pump water through the pipe.
