How Energy conversion from coal is done?

Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...

How Bulletproof glass works?

Shattering the science behind what makes the breakable unbreakable Bullet-resistant glass works by absorbing a bullet’s kinetic (movement) energy and dissipating it across a larger area. Multiple layers of toughened glass are reinforced with alternated layers of polycarbonate – a tough but ﬂ exible transparent plastic which retains the see-through properties of glass. As a bullet strikes the ﬁ rst glass layer, the polycarbonate layer behind it forces the glass to shatter internally rather than outwards. This process absorbs some of the bullet’s kinetic energy. The high velocity impact also ﬂ attens the bullet’s head. Imagine trying to pierce through a sheet of cotton with the top end of a pencil. It would be very difﬁ cult compared to using the sharp pointed end. The same principle applies here. The ﬂ at-headed bullet struggles to penetrate the layer of polycarbonate. As the bullet travels through each layer of glass and polycarbonate, the process is repeated until it no l...
