What is Venturimeter? | Definition, Advantages, Disadvantages – Hydrodynamics
We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.
Venturimeter Definition:
It is a device used for measuring the rate of flow of liquid through pipes. Its working is based on Bernoulli’s theorem.
Rate of flow of liquid,
v = a1a2\(\sqrt{\frac{2 g h}{a_{1}^{2}-a_{2}^{2}}}\)
where, a1 and a2 are area of cross-sections of tube at broader and narrower part and h is difference of liquid columns in vertical tubes.
Advantages:
- Low losses.
- Suitable for the large diameter of the pipe.
- It can be installed vertically, horizontally, inclined.
- Less chance of getting stuck with sediment.
Disadvantages:
- They are large in size and, therefore, where space is limited, they can not be used.
- Maintenance is not easy.
- Required more space.
- It is expensive in installation and replacement.
- It is not suitable for pipe diameter below then 75mm.
Hydrodynamics:
In physics, hydrodynamics of fluid dynamics explains the mechanism of fluid such as flow of liquids and gases. It has a wide range of applications such as evaluating forces and momentum on aircraft, prediction of weather, etc.
