常州wry熱油泵,高溫導(dǎo)熱油泵/國(guó)內(nèi)企業(yè)/ら常州市武研熱油泵有限公司る關(guān)于常州wry熱油泵,高溫導(dǎo)熱油泵/國(guó)內(nèi)企業(yè)/的相關(guān)名詞:什么叫流體密度?密度是指:?jiǎn)挝惑w積內(nèi)的物體所具有的質(zhì)量,如果用G表示物體的質(zhì)量,V表示物體的體積,那么物體的密度ρ可用ρ=G/V表示。密度的單位通常用千克/立方米或克/立方厘米表示。一般情況下,流體的密度會(huì)隨溫度變化而變化,溫度越高,密度就越小,相反地,溫度下降的越低,則密度就變得越大。常州wry熱油泵,高溫導(dǎo)熱油泵/國(guó)內(nèi)企業(yè)/.What is fluid density? Density is defined as: volume per unit volume of the object with the quality, if G said object quality, V represents the object, the density of the object P available P =G/V said. The density of the unit is usually expressed in kilograms / M 3 or g / cm 3. In general, fluid density changes with the temperature, the higher the temperature, the smaller the density, and vice versa, the lower the temperature, the greater the density becomes.
