WebThermoforming is a generic name for shaping a sheet of plastic which has been heated until soft [1]. When soft and pliable, the sheet is stretched over or into a cool mold. Once the material has adopted the shape of the mold it is cooled, so that it retains its new shape. This is why the process is called thermoforming — forming by means of heat. WebOct 14, 2024 · So the water is stationary. In this situation, the pressure at both the points A and B will be the same, which is ${\rho gh}$. Where ${\rho}$ is the density of water. In fig.b, the mercury is removed from the manometer. So water flows out. In this situation, pressure at A is not equal to pressure at B. Even though A and B are at the same level.
