1. What is Discharge Through Section For Steady Incompressible Fluid?

Discharge of fluid, also known as volumetric flow rate, is a measure of the volume of fluid passing through a given cross-sectional area per unit time. For steady incompressible fluids, this relationship is linear and follows the continuity equation.

2. How Does the Calculator Work?

The calculator uses the fundamental fluid mechanics equation:

\[ Q = A_{cs} \times u_{fluid} \]

Where:

\( Q \) — Discharge of fluid (m³/s)
\( A_{cs} \) — Cross-sectional area (m²)
\( u_{fluid} \) — Fluid velocity (m/s)

Explanation: The discharge is simply the product of the cross-sectional area through which the fluid flows and the average velocity of the fluid at that section.

3. Importance of Fluid Discharge Calculation

Details: Accurate discharge calculation is crucial for designing piping systems, water supply networks, hydraulic structures, and various industrial processes involving fluid transport.

4. Using the Calculator

Tips: Enter cross-sectional area in square meters (m²) and fluid velocity in meters per second (m/s). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between discharge and flow rate?
A: Discharge specifically refers to volumetric flow rate, which is the volume of fluid passing through a section per unit time, typically measured in m³/s.

Q2: Does this formula work for compressible fluids?
A: This simplified formula is specifically for incompressible fluids. For compressible fluids, density variations must be considered.

Q3: What if the velocity is not uniform across the section?
A: For non-uniform velocity distributions, the average velocity across the cross-section should be used in the calculation.

Q4: How does this relate to the continuity equation?
A: This is essentially the continuity equation for steady incompressible flow, where mass flow rate remains constant throughout the system.

Q5: What are typical units for fluid discharge?
A: Common units include cubic meters per second (m³/s), liters per second (L/s), gallons per minute (GPM), and cubic feet per second (cfs).
