Hydrostatic Bench and It Accessories Vocational Training Equipment Hydrodynamics Lab

ZM7128 Hydrostatic Bench and It Accessories Vocational Training Equipment Hydrodynamics Lab

I.Equipment overview

This product is used in experiments in the field of hydrostatics to analyze phenomena caused by hydrostatic pressure and to determine the effects of stress.

II.Using instructions

1. Add tap water to the water tank and observe the water level through the water level observation tube. The water level should be higher than the water pump inlet.

(1) Close all valves in the above figure

(2) Control the flow of water into the transparent cylinder of different diameters through the ball valve and observe the reading of the pressure gauge.

III.Various spare parts and its using instructions

1. General hydrometer

The hydrometer is made according to Archimedes’ law and the condition that the object floats on the liquid surface and is an instrument for measuring the density of the liquid. It is a closed glass tube with uniform thickness at one end and scale paper on the inner wall. The scale is uneven, the top is dense and dense, and the other head is slightly expanded and foamed. The bubble is filled with small lead particles or mercury to make the glass tube It is vertically immersed in the liquid to be tested to a sufficient depth and stably floats in the liquid, that is, when it is subjected to any shaking, it can automatically return to a vertical rest position. When the hydrometer floats in a liquid, its own gravity is equal to the gravity of the liquid it is draining. So different depths are immersed in different liquids, and the pressure is different. The hydrometer uses the scale of this relationship.
