Kilowatt hour

The kilowatt hour (symbol kWh, kW·h, or kW h) is a derived unit of energy equal to 3.6 megajoules. If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt-hours is the product of the power in kilowatts and the time in hours. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

Definition

The kilowatt-hour (symbolized kW⋅h) is a unit of energy equivalent to one kilowatt (1 kW) of power sustained for one hour.

One watt is equal to 1 J/s. One kilowatt-hour is 3.6 megajoules, which is the amount of energy converted if work is done at an average rate of one thousand watts for one hour.

Note that the international standard SI unit of energy is the joule. The hour is a unit of time "outside the SI", so the kilowatt-hour is a non-SI unit of energy. It is not listed among the non-SI units accepted by the BIPM for use with the SI.

Examples

An electric heater rated at 1000 watts (1 kilowatt), operating for one hour uses one kilowatt-hour (equivalent to 3.6 megajoules) of energy. A television rated at 100 watts operating for 10 hours continuously uses one kilowatt-hour. A 40-watt light bulb operating continuously for 25 hours uses one kilowatt-hour.

Five Ws

The Five Ws, Five Ws and one H, or the Six Ws are questions whose answers are considered basic in information-gathering. They are often mentioned in journalism (cf. news style), research, and police investigations. They constitute a formula for getting the complete story on a subject. According to the principle of the Five Ws, a report can only be considered complete if it answers these questions starting with an interrogative word:

Some authors add a sixth question, “how”, to the list, though "how" can also be covered by "what", "when", or "where":

Each question should have a factual answer — facts necessary to include for a report to be considered complete. Importantly, none of these questions can be answered with a simple "yes" or "no".

In the United Kingdom (excluding Scotland), the Five Ws are used in Key Stage 2 and Key Stage 3 lessons.

W postcode area

Postcode district boundaries: Bing / Google

The W (Western and Paddington) postcode area, also known as the London W postcode area is a group of postcode districts covering part of central and part of west London, England. The area originates from the Western (W1) and Paddington (W2-14) districts of the London postal district.

Postal administration

The Western district consists of the single original W1 postal district. The area it covers is of very high density development and it has been subdivided into a number of smaller postcode districts. Where districts are used for purposes other than the sorting of mail, such as use as a geographic reference and on street signs, the W1 subdivisions continue to be classed as one 'district'. In June 2000 there was a recoding of the area with the W1M, W1N, W1P, W1R, W1V, W1X and W1Y districts replaced.

The mail centre for W1 is London Central and for W2-14 is Greenford.

Deliveries for W1 (and for WC1 and WC2) came from the Western District Office office on Rathbone Place, until it was decommissioned. This office was a stop on the former London Post Office Railway, which has been mothballed since 2003. The Western District Office was initially located on Wimpole Street, which was also a stop on the London Post Office Railway.

W. H. D. Rouse

William Henry Denham (W. H. D.) Rouse (/raʊz/; 30 May 1863 – 10 February 1950) was a pioneering British teacher who advocated the use of the Direct Method of teaching Latin and Greek.

Life

Born in Calcutta, India on 30 May 1863, when the family returned home on leave to Britain Rouse was sent to Regent's Park College in London, where he studied as a lay student. In 1881 he gained a scholarship to Christ's College, Cambridge. Rouse gained a double first in the Classical Tripos at the University of Cambridge, where he also studied Sanskrit. He became a Fellow of Christ's College, Cambridge in 1888.

After brief spells at Bedford School (1886-1888) and Cheltenham College (1890-1895), he became a schoolmaster at Rugby School, where he encouraged Arthur Ransome - against his parents' wishes - to become a writer. Ransome later wrote, "My greatest piece of good fortune in coming to Rugby was that I passed so low into the school ... that I came at once into the hands of a most remarkable man whom I might otherwise never have met. This was Dr W.H.D. Rouse."
