    Notes: Summary Concern about the environmental damage caused by acid deposition has lead to national programmes to reduce acid precursor emissions. In the UK, a retrofit programme of flue gas desulphurisation (FGD) to three 2,000 MW coal-fired power stations has been announced, with up to four new stations equipped with FGD likely to follow by the year 2000. Whilst the positive effects of acid deposition abatement are recognised there has been considerable concern over the negative aspects of the programme arising, particularly, from the raw material requirements of an FGD plant and the need to dispose of waste products. A careful choice of the most appropriate technology can significantly reduce the negative impacts but such a choice can only be made after an environmental assessment of the national FGD programme.

    Description: Part 1 is to present the results of tests on 56 types of core in a form convenient for use in the study of the performance of and possible improvements in existing designs. Working rules are given by which the data contained in the report may be used, and the most obvious conclusions as to the behavior of cores are summarized. Part 2 presents the results of tests made to determine the pressure necessary to produce water flows up to 50 gallons per minute through an 8-inch square section of radiator core. These data are of special value in evaluating the hydraulic head against which the circulating pump is required to operate.

    Description: Report presents the summation of results obtained in the testing of fuels of various compositions and characteristics in the altitude laboratory. The data upon which this report is based has had an important influence upon the writing of specifications for the various grades of aviation fuels.

    Description: As an airplane rises to high altitudes the decrease in the density and the temperature of the air have important effects on the performance of the radiator. This report gives the results of a study of the effect of reduced pressure and temperature upon the capacity of airplane radiators. A method is presented by which the performance of a radiator at an altitude may be estimated for a particular speed of the airplane at a particular altitude.
