F3 Viscosity decreases with p ressure (at temp eratures below 33 Water's p ressure-viscosity behavior [534] can be explained by the in creased p ressure (up to about 150 MPa) caus ing deformatio n, so reduci ng the stre ngth of the hydroge n-bon ded n etwork, which is also p artially res pon sible for the viscosity. This reduct ion in cohesivity more tha n compen sates for the reduced void volume. It is thus a direct con seque nee of the bala nee betwee n hydroge n bonding effects and the van der Waals dis persion forces [558] in water; hydroge n bonding p revaili ng at lower temp eratures and p ressures. At higher p ressures (and den sities), the bala nee betwee n hydroge n bonding effects and the van der Waals dis persi on forces is tipped in favor of the dis persion forces and the rema ining hydroge n bonds are stron ger due Viscous flow occurs by molecules movi ng through the voids that exist betwee n them. As the p ressure in creases, the volume decreases and the volume of these voids reduces, so no rmally in creas ing p ressure in creases the viscosity. |:| k -二 _ r 1 3ire S C 去 * . i i screr - 丁" \ . / . 一 '气：r J J: V .； r "舄 ■ 3 口二 K n PV ■ ■ L T 三 n 曲 ? ■ 5 M r 丐 町寸 -； J 百* " T N ； 【 I bl ■呻口 " 口寸津 a “ d c i 0 290 八 rao 800 i woo Pressure, MPa g 亠 C) Co? 4 — □ ] J %一 M J s 」气1 □ u 古 气 a 15 ?” ”〕 阳 "1 ■ \ ■ ID % ;: s' ￥ 口『 屮 n ◎ 9 r 奇 * =' f f- ::[ 丄 备 IT 记 |B - 3 D ■i 电- 'u O 丰759勺； 】I -一 11 L .

360 109 370 264 F3 Viscosity decreases with pressure (at temperatures below 33°C) Viscous flow occurs by molecules moving through the voids that exist between them. As the pressure increases, the volume decreases and the volume of these voids reduces, so normally increasing pressure increases the viscosity. Water's pressure-viscosity behavior [] can be explained by the increased pressure (up to about 150 MPa) causing deformation, so reducing the strength of the hydrogen-bonded network, which is also partially responsible for the viscosity. This reduction in cohesivity more than compensates for the reduced void volume. It is thus a direct consequence of the between hydrogen bonding effects and the van der Waals dispersion forces [] in water; hydrogen bonding prevailing at lower
