Description: Simple physics simulation concerning the hydrostatic pressure in liquids. Moving a manometer downward in a container
filled with a given liquid and reading the pressure for this depth, shows that the hydrostatic pressure linearly increases with the depth, and also directly
depends on the liquid's density: p = gρh.
You can choose one of some common liquids with given density or enter a custom value. Depth may be entered manually or by moving a trackbar. The hydrostatic pressure may be displayed in either hP, atm or mm Hg.
Free Pascal features: Usage of trackbars. Using the Top property of controls to simulate their vertical
movement. Changing the size of shapes during runtime. Changing controls' properties in order to create simple simulations.
