How to Calculate Hydrostatic Pressure?
Follow the steps provided below to calculate the hydrostatic pressure of a manometer easily.
- Find the type of manometer, the place manometer is attached to, atmosphereric pressure, density and height of the liquid from the question.
- Multiply the liquid density, acceleration due to gravity and liquid height.
- The obtained product is called the pressure of the liquid.
What is Manometer?
A manometer is a simple tool that is used to measure fluid pressure. It has a uniform glass tube attached to a pipe. It is nothing but a tube that is used to measure pressure differences due to the interaction of fluids and atmospheric pressure. Usually, a manometer has high-density liquid mercury and it may also have water or any other liquid.
A manometer works by following Pascal's principle. Pascal's principle states that the pressure applied on a part of an enclosed incompressible liquid will be transmitted equally in all directions through the fluid.
One of the best examples of a manometer is toothpaste. The formulas or hydrostatic pressure equations to compute the manometer pressure are along the lines
P = ρgh
The pressure equation for u-tube manometer attached to pipe P = ρ1 * g * h1 + (-)ρ2 * g * h2
Where,
P is the pressure of the liquid
h is the height
ρ is the liuid density
g is the acceleration due to gravity
Example
Question: In a single column manomer, one end is attached to the atmosphere and the other is an open tank. If the atmospheric pressure is 1025 Pa and liquid, liquid density is 1050 kg/m3 and the liquid height is 0.2 m, find the gauge pressure and absolute pressure?
Solution:
Given that
Atmospheric Pressure = 1025 Pa
Liquid density = 1050 kg/m3
Liquid height = 0.2 m
Gauge Pressure is P = ρgh
Substitute the values in the formula
P = 1050 * 0.2 * 9.8
P = 2058 Pa
Absolute pressure = 2058 - 1025
= 1033 Pa
Therefore, gauge pressure is 2058 Pa and absolute pressure is 2033 Pa

FAQ's on Manometer Calculator
1. What are the types of manometers?
The different types of manometer are U-tube manometer, small manometer, inverted U-tube manometer, differential U-tube manometer and inclined manometer.
2. How to calculate pressure using a manometer?
The formula to calculate the pressure using a manometer is density * acceleration due to gravity * liquid height. You need to find the product of these three parameters to get the pressure.
3. What is the difference between a manometer and a barometer?
The barometer is a kind of closed type manometer. A manometer is a pressure instrument designed for measuring fluids pressure. A barometer is specially designed for measuring atmospheric pressure.
4. How to use the manometer calculator?
You just need to enter all the required details in the input fields and tap on the calculate button. The result will be the gauge pressure and absolute pressure acting the fluids.
