    After the Bhopal gas disaster in 1984‚ the Indian legislation governing safety and environment underwent significant changes.Specifically‚the factories Act was amended to assign the responsibility of the “occupier”‚who is legally responsible for the safety of the workplace and workers‚to the highest level of management in an organization. For a company this meant that one of the directors on the board had to be designated as “occupier”.The Environmental legislation also underwent changes ‚with the

    5. Combustion of liquid fuels 5.1 Atomization of fuel Liquid fuels such as gasoline‚ diesel‚ fuel oil light‚ fuel oil heavy or kerosene have to be atomized and well mixed with the combustion air before burned. Therefor nozzles are used. Nozzles are divided into two groups: Pressure atomizers and twin-fluid atomizers. 5.1.1 Pressure atomizers Pressure atomizers are differed into turbulence nozzles and liquid sheet nozzles. At both types of nozzles the energy from the liquid pressure is converted

    time relate to the change in temperature of H2O as it changes phases from ice to water to gas? Hypothesis If the time which H2O stays on the hot plate increases‚ then the temperature of H2O will increase and the phases from ice to water to gas will change because the heat is a source of energy to change the physical states. Background Ice is a solid form of H2O and water is a liquid form of H2O. The gas form of H2O is water vapor. A solid has a definite volume and shape. It is not compressible

    and efficiency of the precipitator is reduced. The precipitator has 99% efficiency and can be operated at high temperature (600° C). It is more economical and simple to use. WET COLLECTORS OR SCRUBBERS – Wet collectors remove particulates from gas stream by incorporating the particles into liquid droplets directly on contact. The collection efficiency of a wet collector is a function of the energy consumed in the air to water contact process. The energy consumed is directly proportional to the

    A critical point happens when a substance has a high enough temperature and pressure that both liquid and gas can exist at the same time. This state is called a critical point. Now‚ when a state of matter changes from one state to another is called a phase shift. Phase shifts are extremely important and most commonly observe phase shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand

    PHYSICS FORM: 4D & 4E TOPIC: THERMAL PHYSICS Temperature determines the direction of net heat flow. It is the property o f an object. It’s the amount of kinetic energy a body possesses. Example Brass rod made hot at one end by placing it in a Bunsen flame‚ while other end is kept away at room temperature‚ there is a net transfer of energy from the high temperature region to the low temperature end. THERMAL EXPANSION (See chp. 16 in Physics Text). Three states of matter are solids

    air as an ideal gas. In a real engine inlet flow may be all air‚ or it may be mixed‚ up with 7% fuel‚ either gaseous or as liquid droplets‚ or both. In air-standard analysis‚ even if all fluid in an engine cycle were air‚ some error would be introduced by assuming it to be an ideal gas with constant specific heats. At the low pressures of inlet and exhaust‚ air can accurately be treated as an ideal gas‚ but at the higher pressures during combustion‚ air will deviate from ideal gas behavior. A more
