Electrical Energy01:10

Electrical Energy

Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules. The...

Energy Basics

Chemical reactions, such as those that occur when you light a match, involve changes in energy as well as matter.

Power

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...
Energy Conservation and Bernoulli's Equation01:16

Energy Conservation and Bernoulli's Equation

Applying the conservation of energy principle or the work-energy theorem to an incompressible, inviscid fluid in laminar, steady, irrotational flow leads to Bernoulli's equation. It states that the sum of the fluid pressure, potential, and kinetic energy per unit volume is constant along a streamline.
All the terms in the equation have the dimension of energy per unit volume. The kinetic energy per unit volume is called the kinetic energy density, and the potential energy per unit volume is...
Application of the Energy Equation01:04

Application of the Energy Equation

The application of the energy equation to centrifugal pumps is a fundamental principle in fluid dynamics and engineering. In this scenario, the energy equation is used to calculate the flow rate of a centrifugal pump responsible for transferring water between two reservoirs at different elevations. The pump applies an energy input of 7500 joules per second, and the vertical difference between the lower and upper reservoirs is 10 meters. Additionally, the head loss due to friction and other...
Power and Energy01:12

Power and Energy

The power and energy delivered to an element are subjects of great significance in the field of electrical engineering. It is a well-known fact that a 100-watt light bulb emits more light than a 60-watt one. Therefore, power and energy calculations play a crucial role in the analysis of electrical circuits.
Power, defined as the time rate of expending or absorbing energy, is quantified in units called watts (W). The relation between power and energy is mathematically given as

  • Sustainable Building Operations

Background:

  • The National Health Service (NHS) faces significant challenges with escalating energy costs and a large carbon footprint.
  • Existing Building Energy Management Systems (BEMS) are often underutilized or not operating at peak performance.

Purpose of the Study:

  • To highlight the potential of optimizing existing BEMS to address NHS energy cost and carbon footprint challenges.
  • To demonstrate that improved BEMS operation can lead to substantial financial and environmental benefits.

Main Methods:

  • Analysis of current BEMS performance within NHS facilities.
  • Identification of key areas for operational optimization.
  • Case study or theoretical modeling of savings achievable through enhanced BEMS functionality.

Main Results:

  • Optimizing existing BEMS can lead to considerable reductions in energy consumption.
  • Improved BEMS performance directly translates to significant cost savings for healthcare facilities.
  • Enhanced operational efficiency of BEMS contributes to a reduced carbon footprint.

Conclusions:

  • Making better use of existing BEMS is a viable and cost-effective strategy for the NHS.
  • Substantial savings and environmental benefits can be achieved through BEMS optimization without additional capital investment.
