1. How is pressure calculated?
Answers
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A.
please mark as brainliest answer
Explanation:
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. ... You don't have to be underwater to experience pressure from a fluid.
Method 2 Finding the Density of your Liquid
Measure the volume of your liquid. Pour 100 mL of liquid into a pre-weighed graduated cylinder. ...
Weigh the liquid. Put the sample of liquid on a scale. ...
Calculate the liquid's density. Density is equal to the mass of the liquid divided by the volume of the liquid.
Use the hydrostatic pressure formula P = pgh, where p is the density of water in kg per cubic meter, g is the gravitational acceleration constant, h is the height of the water above the valve in meters and P is the pressure in pascals.
