how to calculate pressure and volume. In the foot-pound-second FPS system the units are pounds per square inch or psi. A conversion scale will also appear and reset when any of the input parameters for volume or flow rate are changed.
PV nRT where P pressure V volume n moles of gas T temperature R 8314 J K-1 mol-1 ideal gas constant. Then the equation of Boyles law states that. A pressure change then reduces the volume to 22 gallons.
P 1 V 1 P 2 V 2.
The new pressure P 2 remains unknown. Using the calculator we click on V₂ because we are calculating the present volume. The volume of 100 mol of any gas at STP Standard temperature 27315 K and pressure 1 atm is measured to be 22414 L. The downward force acting on this region due to the fluid above the region is equal to the pressure times the area of contact.
