How to Calculate the Fluid Acceleration Field

When calculating the velocity of a fluid, you need to first determine how the fluid is being transported. Most fluids travel through a pipe or hose using a measurement of feet per second. Water is a type of fluid whose velocity you can calculate using a mathematical equation. However, this equation will require specific variables that you will need to obtain before it can be solved.

Instructions

- 1
  Write out the equation for calculating the velocity of a fluid. This is expressed as V = Q x 0.408/D^2.
- 2
  Input the flow rate of the pipe or hose in gpm for the letter ̶0;Q̶1; in the equation. As an example, you can use 50 gallons that flow through the pipe or hose per minute.
- 3
  Input the diameter of the pipe or hose for the letter ̶0;D̶1; in the equation. As an example, the diameter or a pipe or hose is 4 inches. Multiply 4 by itself to obtain ̶0;D^2,̶1; which is 16.
- 4
  Write out the completed equation for calculating the velocity of a fluid. In this case, this equation will look like ̶0;V = 50 x 0.408/16.̶1; The result of the equation is 1.275 feet per second in this example.
