FORCE DEVIDED BY AREA
it is called a barometer the constuction u can find many places on net a manometer is also used to measure pressure of gases
oBecause chemistry just does that , I mean you cant exactly change what Chemistry says! You know what just go find your Chemistry book and find out and Get off of the Internet!Dimwits -__--Trill>.
using a pressure gauge.
it depends on what your dealing with, room pressure is found with a barometer, to measure pressure in a flowing fluid, you can use a manometer. there are many variou ways to find pressure, but you must be specific on the circumstances
A well-type manometer is to be used to measure differential pressure in a water flow system. The manometer uses a special bromide liquid of specific gravity of 2.95.The well and tube are of 75 mm and 5 mm diameter respectively. The scale placed along the tube has no correction factor for the area ratio of the manometer. Calculate the value of this factor which must be multiplied by the manometer reading in mm to find the pressure differential in kg/cm2.
You can find Dynamic pressure by using bernoulli's equation. P = (density * velocity^2)/2
Pascals are a unit of pressure. pressure = Force / area being acted on. Therefore: Force = Pressure x Area being acted upon.

Below is the solution using eculator(Find Pressure from Area, Force.)Using the expression(see reference): P = F/Awhere:F is the Force = 60 NA is the Area = 20 m²we calculate the value for Pressure(P):P = 60/20∴ P = 3.0Final Answer :3.0 Pascal
The website http://allrecipes.com//Recipes/everyday-cooking/pressure-cooker/Main.aspx has some great recipes available. They are easy to make and very simple when using the pressure cooker.
Pressures simply add. If the partial pressure of gas is three and the partial pressure of water is five, the total pressure is eight. Find the partial pressure for water at the temperature of your experiment, subtract it from your pressure reading. As an aside, if you've corked your glassware rather than using a slider or a water bath, expect stupid results.
pressure =force/ area pressure of a liquid is density time height.
