1. What is Pressure to Power Conversion?

Definition: This calculator converts fluid pressure difference and flow rate into mechanical power.

Purpose: It helps engineers and technicians determine the power available in fluid systems or required for pumps.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power (Watts, W)
• \( Q \) — Volumetric flow rate (m³/s)
• \( \Delta P \) — Pressure difference (Pascals, Pa)

Explanation: The power is simply the product of flow rate and pressure difference in SI units.

3. Importance of Pressure to Power Conversion

Details: This calculation is fundamental in hydraulic systems, pump sizing, and energy analysis of fluid flow systems.

4. Using the Calculator

Tips: Enter the flow rate in m³/s and pressure difference in Pascals. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical units for this calculation?
A: SI units are used (m³/s for flow, Pa for pressure, W for power). For other units, convert first.

Q2: Does this account for system efficiency?
A: No, this gives theoretical power. Actual power requirements would be higher due to inefficiencies.

Q3: Can I use this for gases?
A: Yes, as long as the flow is incompressible or pressure changes are small relative to absolute pressure.

Q4: How does this relate to pump power?
A: This gives the hydraulic power. Pump shaft power would be this divided by pump efficiency.

Q5: What's a practical example?
A: A pump moving 0.01 m³/s against 100,000 Pa (1 bar) delivers 1,000 W (1 kW) of hydraulic power.
