P = ρ g h：液体密度 ρ（淡水 1000，海水约 1025 kg/m³）、深度 h；同时给出加上大气压后的绝对压力。本地处理。P = ρ g h for fluid density ρ (fresh water 1000, seawater about 1025 kg/m³) and depth h; plus the absolute pressure including the atmosphere. Processed locally.
使用说明与常见问题How-to & FAQ
「液体静压力」是什么？What is the Hydrostatic Pressure Calculator tool?
P = ρ g h：液体密度 ρ（淡水 1000，海水约 1025 kg/m³）、深度 h；同时给出加上大气压后的绝对压力。本地处理。P = ρ g h for fluid density ρ (fresh water 1000, seawater about 1025 kg/m³) and depth h; plus the absolute pressure including the atmosphere. Processed locally.
如何使用「液体静压力」？How do I use the Hydrostatic Pressure Calculator tool?
在「液体静压力」中，填写「密度 kg/m³」、「深度 m」、「大气压 kPa」等参数，结果会随输入实时计算并显示在下方。In the Hydrostatic Pressure Calculator: Fill in "Density kg/m³", "Depth m", "Atmospheric pressure kPa"; results are recalculated instantly as you type.
每 10 米？Every 10 m?
淡水中每下潜约 10 m，压力增加约 1 atm。In fresh water pressure rises about 1 atm every 10 m.
能举个计算实例吗？Can you show a worked example?
例如在「液体静压力」中填 密度 kg/m³ = 1000，深度 m = 10，大气压 kPa = 101.325，结果区显示：表压：98.07 kPa；绝对压力：199.39 kPa；巴（表压）：0.9807 bar；atm（表压）：0.9678 atmFor example, entering Density kg/m³ = 1000, Depth m = 10, Atmospheric pressure kPa = 101.325 in the Hydrostatic Pressure Calculator gives: Gauge pressure: 98.07 kPa; Absolute pressure: 199.39 kPa; Bar (gauge): 0.9807 bar; atm (gauge): 0.9678 atm
哪些输入会被检查？Which inputs are validated?
「液体静压力」会检查这些输入——「密度 kg/m³」：必须填写，须大于 0；「深度 m」：必须填写；「大气压 kPa」：必须填写，不能为负数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Hydrostatic Pressure Calculator checks its inputs — "Density kg/m³": required, must be greater than 0; "Depth m": required; "Atmospheric pressure kPa": required, cannot be negative; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「液体静压力」的设置：「密度 kg/m³」默认 1000；「深度 m」默认 10；「大气压 kPa」默认 101.325。每次生成结果都按当前设置处理。Settings in the Hydrostatic Pressure Calculator — "Density kg/m³" default 1000; "Depth m" default 10; "Atmospheric pressure kPa" default 101.325. The result always uses the current settings.
计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?
「液体静压力」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Hydrostatic Pressure Calculator uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
「液体静压力」免费吗？需要注册吗？Is the Hydrostatic Pressure Calculator free? Do I need an account?
