1. What is Drag Force on Body in Fluid?

Drag Force on Body in Fluid is the resisting force experienced by an object moving through a fluid. It opposes the motion of the object and depends on factors such as the object's shape, size, velocity, and the properties of the fluid.

2. How Does the Calculator Work?

The calculator uses the Drag Force formula:

\[ F_D' = \frac{C_D' \times A_p \times M_w \times v^2}{V_w \times 2} \]

Where:

\( F_D' \) — Drag Force on Body in Fluid (N)
\( C_D' \) — Coefficient of Drag for Body in Fluid
\( A_p \) — Projected Area of Body (m²)
\( M_w \) — Mass of Flowing Fluid (kg)
\( v \) — Velocity of Body or Fluid (m/s)
\( V_w \) — Volume of Flowing Fluid (m³)

Explanation: The formula calculates the drag force experienced by a body moving through a fluid based on its drag coefficient, projected area, fluid properties, and velocity.

3. Importance of Drag Force Calculation

Details: Accurate drag force calculation is crucial for designing vehicles, aircraft, ships, and other objects that move through fluids. It helps in optimizing performance, efficiency, and stability.

4. Using the Calculator

Tips: Enter the coefficient of drag, projected area, mass of flowing fluid, velocity, and volume of flowing fluid. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect the drag coefficient?
A: The drag coefficient depends on the shape of the object, surface roughness, Reynolds number, and fluid properties.

Q2: How does velocity affect drag force?
A: Drag force is proportional to the square of velocity, meaning it increases rapidly with higher speeds.

Q3: What is projected area?
A: Projected area is the two-dimensional area of a three-dimensional object as seen from the direction of fluid flow.

Q4: When is this formula applicable?
A: This formula is applicable for calculating drag force on bodies moving through fluids in various engineering applications.

Q5: Are there different types of drag?
A: Yes, there are different types of drag including form drag, skin friction drag, and wave drag, each with different characteristics.
