Description: A new method to measure the fall velocity of small water drops and an improved method to measure their size distribution are discussed in this paper. The oil-microscope method is an improvement over the oil method of Eigel and Moore (1983) to detennine small water drop sizes and their distribution, while a newly developed videocamera method was used to measure the fall velocity of small water drops. Both methods are simple and direct, and give quick and accurate results. The only equipment required for the oil-microscope method is a standard optical microscope. This method is especially useful to measure the size of very small water drops (less than 0.5 mm in diameter), which is not easily achievable by other methods. The smallest drop size measured in this study was 0.03 mm in diameter. The videocamera method requires only fairly standard equipment (stroboscope, videocamera, monitor, and videocassette recorder) and has the advantage of being appropriate for very small water drops. Both methods can be readily used either in the field or in the laboratory.
