The Letter Report When is it appropriate? Who is the audience?
Characteristics • 3-5 pages • 0-3 tables or figures • emphasize important points • avoid details • choose words carefully • avoid repetition • Concise Writing!
No Title Page • no title • authors sign letter • date is in letter format • affiliation is in letterhead • position is with signature
No Headings or Numbered Sections • no table of contents • no list of figures • no list of tables • no list of references • Use footnotes
Summary and Introduction • no separate sections • must present purpose and state important results early in the paper (first paragraph) • lacks repetition of a formal report
References • treated as footnotes • only a few references • no list of references
Tables and Figures • same format as in other reports • Few in number! • Only the important ones • should be self-contained documents • place • at end of letter • or within letter
No Nomenclature Section • all symbols must be defined as they are introduced • use only important equations
Backup Information • raw data • calculations • error analysis • experimental equipment • experimental procedures
Outline • recipient and address • salutation • project objective • important results • description of experimental procedures - very brief, innovative techniques, problems encountered
Outline continued • results - analysis - discussion • recommendations • signature
205 East 2nd South Apt 6 SLC, Utah 84103 February 6, 1992 Professor Noel de Nevers Department of Chemical Engineering University of Utah Salt Lake City, Utah 84112 Dear Dr. de Nevers: During the period from January 6 to January 27, 1992, the members of Group F calibrated and evaluated the performance of an Omega Model HX93V relative-humidity and temperature transmitter (Omega Engineer., Stamford Connecticut). The transmitter was calibrated with an Omega HX92-CAL relative-humidity calibration kit, and its accuracy was tested with various solutions of ethylene glycol and water ranging from 10% to 100% relative humidity (RH). The transmitter was accurate to within 5%
RH at higher relative humidities (>50%) but was not accurate to within 5% RH at humidities lower than 50%. The transmitter's performance in a moving airstream at temperatures greater than room temperature was also investigated. A cardboard tube and an air blower containing a heating element supplied a suitable stream of heated air. A brief summary of the calibration and the results of our performance evaluation follow: …….
