Fluid Pressure Vs Depth
Purpose
To demonstrate that the fluid pressure increases linearly with depth and that pressure is isotropic.
Equipment
Glass tube connected to manometer, water tank.

Description
An L-shaped glass tube connected to a liquid manometer is inserted into a tank of
water. The pressure in the water tank can be measured at any depth. Holding the tube
at a particular depth and rotating it about the end will show no change in pressure,
demonstrating that pressure is isotropic.◙
