Activation energy

Theory: Boyle’s Law states that when temperature (T) is kept constant, pressure (P) and volume (V) have an inversely proportional relationship. Boyle’s constant (B) can be expressed by V=B/Pwhere volume is (in this lab) cm^3 and pressure is in atm. Charles’ Law states that when pressure is held constant, temperature and volume are directly proportional. Charles’ constant (C ) can be expressed by V=CTwhere volume is in cm^3 and temperature is in Kelvin. Gay-Lussac’s Law states that when…

Theoretically, energy in every isolated system will always be conserved so for every action there will be a reaction to stabilise the system (Ellert, G, n.d.). Such a term does also appear in the physics of fluids motion. Fluids are things that can flow such as gas, water or oil. In fluid motion physics there are two theories that are involved with the law of conservation and they are Bernoulli’s law and continuity equation. Bernoulli’s law is derived from the energy conservation between…

Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a rigid body Similarities - Conservation of energy -…

2.1. Theoretical Background 2.2. Material Selection Material selection plays an important role as the humidifier has to deal with a pressure of 2 Bar and temperature ranging from ambient to 90oC (maximum) and have to bare a load of 80 Newton. Simultaneously it should be lighter than aluminum and should be cheaper and fabricating time should be less and it should be capable of mass production and before all this it should serve the purpose. when developing plastic parts. Selection of an…

3.3.2. Initial and Boundary Conditions. The pipe is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to…

Presentation of non-conventional welding procedures applied a. Friction welding Friction welding is a pressure welding procedure, at which the energy necessary for welding is obtained by transforming the friction mechanical energy into heat. [1] Welding process includes the following phases: [1]  driving one of the welding components in rotating, with constant or variable speed and the other one (fixed) pressing on it, with an axial…

it is not fair to compare the two systems based purely on the magnitude of its COP as the work required in a VA refrigerator is produced by heat, it is much cheaper than the work required in VC refrigerator which require electrical or mechanical energy. Environmental issue Conventional VC refrigerant such as CFC or HCFC can deplete the ozone layer and is already phased out based on the Montreal Protocol. Modern VC refrigerant like HFC - also known as f-gases (fluorinated greenhouse gases) - has…

The electric skillet is like the electric iron thou it has a little divider surface and a cover that comes close by. The skillet gives this straightforward adjustment contrasted with the frying pan, and this completely changes how these two machines are put into utilization. The skillet can likewise sit over a table, and it gives warmth, and it warms up inside minutes. The dividers help to contain the sustenance that is being cooked, and it's additionally perfect when cooking nourishment with…
