２０μｍ以下の粒子が多く、また含水率１％の油中には
１００μｍ程度の水粒子２が存在している。According to the above-mentioned microscopic observation, the particle size of the water particles 2 mixed in the oil 1 varies depending on the degree of water content, and for example, when the water content is 0.
Most of the water particles 2 contained in oil 1 with a water content of 1% or less have a particle size of 10 to 20 μm or less, and water particles 2 of about 100 μm are present in oil with a water content of 1%.
