Reference excerpt

James Arthur Reavell (10 June 1872—26 August 1973) M.I.Mech.E., M.I.Chem.E., F.Inst.F., F.I.M. was a British chemical engineer, who created a major company and was one of the founders and a president of the Institution of Chemical Engineers.

Life Reavell was born 10 June 1872 in Alnwick, the son of George and Martha Reavell. He attended Alnwick Grammar School and Silcoates School. He married Emma Mabel Clowes on 24 May 1898, and they had two sons, and one daughter. After her death, he married Winifred E. Haydon on 16 August 1941. One of his sons, Brian Noble Reavell, was also a chemical engineer, and took over as chairman when he retired from his business in 1960. He died 26 August 1973.

Career He wanted to be a chemist, but instead served an apprenticeship in electrical engineering, and had several positions, rising to be manager for the European operations of an American chemical engineering company Worthington Pumps then manager of Manlove, Alliott & Co. Ltd., dealing with sugar refining, of which a particular aspect is evaporation. In 1907 he set up his own company Kestner Evaporator and Engineering Co., to deal with the British and Empire market of an improved design of evaporator patented by his friend, French inventor Paul Kestner. During the First World War his engineering expertise was applied to solving the shortage of explosives in a team headed by Lord Moulton. He continued as Chairman of Kestner until 1960, when he stepped down in favour of his son, Brian, but continued as president until 1963. The company made a variety of chemical plants with subsidiaries in Australia and South Africa.

Institutions As Chairman of the Chemical Engineering Group of the Society of Chemical Industry (SCI) he was one of the small group of enthusiasts who founded the Institution of Chemical Engineers, becoming its President 1929. He continued to be active in the SCI, being vice-president from 1931 to 1934. He was also a Member of the Institution of Mechanical Engineers; a Fellow of Institute of Fuel; and a Fellow, Institute of Metals; Chairman of the British Chemical Plant Manufacturers' Association; Chairman of the chemical engineering industry section of the British Standards Institute; and President of the Combustion Appliance Manufacturer's Association from which he formed the British Coal Utilisation Research Association, and was its vice-president.

Worked examples

Example 1 — a first encounter with J. Arthur Reavell

Start with the simplest possible case. Write down what J. Arthur Reavell claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to J. Arthur Reavell before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about J. Arthur Reavell ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of J. Arthur Reavell

In research: J. Arthur Reavell appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses J. Arthur Reavell in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: J. Arthur Reavell is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1872 births, 1973 deaths, British chemical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for J. Arthur Reavell outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
