pascals

1米深水的压力是：9800帕斯卡。压强P=ρgh（ρ密度，ρ=1000千克/立方米，g重力加速度，g=9.8牛顿/千克，h水深，单位米）。1米深水的压力=1000×9.8×1=9800帕斯卡 1个标准大气压的压强=1.013×10^5帕斯卡=10.13米水柱的压力

11. According to the formula for liquid pressure and precise physical values, the specific value of one standard atmosphere is approximately 1.01325×10^5 pascals.

The density is an intensive property which is defined as an object's mass over its unit volume. The symbol of density is ρ.5.what is pressure?5 什么是压力？ANSWER:The pressure 'P' is the force per unit area applied in a direction perpendicular to the surface of an object....
