Biography of James Watt, Inventor of the Modern Steam Engine

3/25/2019 · James Watt (1736-1819) was a Scottish inventor, engineer, and chemist. He developed a workable steam engine which utilized a separate condenser; this innovation made the steam engine a useful tool for a vast range of uses. In many ways, Watt's invention was the technological impetus behind the Industrial Revolution.

Design and layout of pipes for water supply to a building

All water supply systems use a combination of pipes (of different dimensions and materials), valves and outlets to deliver water to building users. Some water supply systems also use storage tanks and pumps. Designing a water supply system involves getting all of these elements right so that clean water is delivered to the user at the appropriate rate and temperature.

Thermal power station

A thermal power station is a power station in which heat energy is converted to electric power.In most of the places in the world the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms.Its chemical formula is H 2 O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds.Water strictly refers to the liquid state of that substance, that prevails at standard ...

Modeling of fire-tube boilers

Highlights A dynamic model has been developed for the analysis of boiler performance. The mathematical model is based on the first principles. The model gives the dynamic performance during nominal operation and the start-up. The model proposed is useful to assist plant engineers and for training operators. A case study of an 800 HP fire-tube boiler was simulated using pulse and step changes.

Boiling water reactor

A boiling water reactor (BWR) uses demineralized water as a coolant and neutron moderator.Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. The steam is directly used to drive a turbine, after which it is cooled in a condenser and converted back to liquid water. This water is then returned to the reactor core, completing the loop.
