    KVA stands for kilo-volt-ampere, which basically is the unit of electric power. While calculating kVA of any piece of equipment the power factor is not taken into account. (i.e.) Power in kVA = Voltage x Current.

    This means kVA is the unit of measurement for that equipment in which the output power is independent of power factor. For example Rating of Alternators, Transformers, and UPS etc. On the other hand, KW (KiloWatts) is also the unit of electric power for that equipment in which power factor plays a role. Normally machines that produce a mechanical output is rated in kilowatts. For example the rating of electric motors. Read More about power factor.

    Power Transformer Transformers are an energy transfer device that transfers power from the primary side to the secondary side without altering the energy level (considering zero power loss). Iron loss and copper loss occurring in the transformer are also independent of the power factor. Moreover, the output power factor of the transformer purely depends on the connected load. The transformer does not alter the power factor of its output power. Transformers are rated in kVA because the losses occurring in the transformers are independent of power factor.

    Power Transformer

    KVA is the unit of apparent power. It is a combination of real power and reactive power. Transformers are manufactured without considering the load being connected. So any kind of electrical load can be connected to it (either resistive, capacitive, inductive or combination loads). If the transformer is rated in KW, there may be confusions regarding the type of load being connected. This is why the transformer is rated in KVA. By doing so we can eliminate the confusions regarding the type of load being connected.

    The definition of technology is science or knowledge put into practical use to solve problems or invent useful tools. It is an application of science to solve a problem. Technology refers to the practical application of scientific knowledge for a purpose. it also includes the capability and skills required to apply the knowledge.

    There is a revolution in civil engineering happening due to technology. From drones to innovative construction materials, be on the looked for how technology will influence, impact and improve the civil engineering industry in twenty first century.

    In recent decay, the most one benefit from technology taken by a civil engineer is software tool in design part.

    Software packages are to the civil engineers what a towel is to a mason. In short, a civil engineer, through a mathematical model, analyze the behavior of construction materials, from the result of these analysis he or she can select the appropriate material and their combination for an efficient design. Software packages streamline these processes, allowing the engineer to do fast and accurate computation using different mathematical model and output them in a human-friendly graphical representation and effectively easing cross-disciplinary collaboration. A design process that could have taken years now could be reduced to a couple of weeks.

    Similarly like design part, the benefit of technology taken by civil engineer in other area are described below.

    i) More efficient daily operations

    In the part, construction companies faced the challenge of creating and sharing design information in real time. Designers and other professional would have to manually draw up sketches, project outlines and illustration. They would then have to send the sketches to relevant personnel and customers for review and approval.

    With construction technology, project managers can use software to co-ordinate projects, share digital sketches and receive feedback in real time. In this way, the daily operations of construction companies large and small are improving significantly.

    Construction technology also allows users to co-ordinate information across departments and with their clients. This results in a less costly and more streamlined daily operational model, with reduced changes orders and miscommunication.

    ii) Smarter and more durable structures

    Construction technologies produce smarter and more durable structures in two main ways:

    a) By designing better from scratch.

    b) By retrofitting existing structures for increased durability

    iii) Use of better tools

    Implementing construction technology is all about taking advantage of the best tools on the market today, and using them to create better work. Whether it’s using 3D imaging to generate more interactive models, laser scanning to facilitate efficient renovations or estimating systems that allow you to reduce costs, there is no shortage of platforms to improve your business.

    iv) Better client services

    For many years, the construction industry has had the challenge of communicating information efficiently to clients; owners would have to frequently visit the construction site to see how their project was proceeding and to ensure high standards of quality.

    v) Innovation

    Much of the innovation in the construction industry is being driven by technological advancements and with new software features added to platforms on a frequent basis, construction professionals are constantly presented with new opportunities for growth.

    An ecosystem is a community of living organisms in conjunction with the non-living components of their environment (things like air, wider and mineral soil), interacting as a system. Ecosystem is a natural unit which consists of biotic communities and their abiotic environment. It is also Basic functional unit in ecology. Energy, water, nitrogen and soil  minerals are other essential abiotic components of an ecosystem. Ecosystem are controlled both by external and internal factors. External factors such as climate, parent material that forms the soil, typography, etc. and internal factors include disturbance, succession and the types of species present.

     

    Characteristics of Ecosystem:

    i) Biotic component: producer (green plants), consumers (animals), decomposers (microorganisms)

    ii) Abiotic component: Air, water, soil

    iii) Energy flow: Sun is the  main source of energy

    iv) Matter

    v) Interrelationship

    vi) Biological integration

    vii) Flexibility

    viii) Ecological regulation

    ix) Smallest unit of biosphere

    x) An open system with a continuous, but variable influx and loss of materials and energy.

    First law of thermodynamics states that during any cycle that a system undergoes, the cyclic integral of the heat equals cyclic integrals of the work. The first law, however, places no restriction on the direction of flow of heat and work. A cycle in which a given amount of heat is transferred from the system and an equal amount of work is done on the system satisfies the first law just as well as a cyclic in which the flow of heat and work are reversed. However, we know from our experience that a proposed cycle that does not violate the first law does not ensure that the cycle will actually occur. It is a kind of experimental evidence that led to the formulation of the second law of thermodynamics. Thus a cycle will occur only if both the first law and second law of thermodynamics are satisfied.

    Consider a hot water glass left in a cooler room that eventually cools off. This process satisfies the first law of thermodynamics as the amount of energy lost by hot water equals amount of heat gained by the surroundings. If we consider a reverse process, i.e., hot water getting even hotter in a cooler room as a result of heat transfer from the room air. It is obvious that this process never takes place. Furthermore, this process does not violet first law of thermodynamics as long as amount heat lost by air equals the amount of heat gained by hot water

    Gasoline is  used as a car drives up hill, but the fuel in gasoline tank cannot be restored to it’s original level when car coasts down the hill. However, this process as well does not violate first law of thermodynamics.

    These arguments clarify that processes proceed in a certain directions and not in the reverse direction. The first law of thermodynamics places no restriction on the direction of a processes and satisfying the first law of thermodynamics does not ensure that the process can actually occur. This inadequacy of the first law of thermodynamics to identify whether a process can take place in remedied by introducing another general principle, called second law of thermodynamics. The reversed processed discussed in above examples violet the second law of thermodynamics.
