1. What is the Efficiency of Jet Pump?

The Efficiency of Jet Pump measures how effectively a jet pump converts input energy into useful work. It represents the ratio of useful output (energy transferred to the fluid) to the input energy supplied to the pump.

2. How Does the Calculator Work?

The calculator uses the Jet Pump Efficiency formula:

\[ \eta = \frac{Q_s \times (h_s + h_d)}{Q_n \times (H - h_d)} \]

Where:

\( \eta \) — Efficiency of Jet Pump
\( Q_s \) — Discharge through Suction Pipe (m³/s)
\( h_s \) — Suction Head (m)
\( h_d \) — Delivery Head (m)
\( Q_n \) — Discharge through Nozzle (m³/s)
\( H \) — Pressure Head on Delivery Side (m)

Explanation: The formula calculates the efficiency by comparing the energy gained by the fluid to the energy supplied through the nozzle.

3. Importance of Jet Pump Efficiency Calculation

Details: Calculating jet pump efficiency is crucial for optimizing pump performance, energy consumption, and system design. It helps in selecting the right pump for specific applications and identifying potential improvements in pump operation.

4. Using the Calculator

Tips: Enter all values in appropriate units (m³/s for discharge, m for heads). Ensure Pressure Head on Delivery Side is greater than Delivery Head for valid calculation. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical efficiency range for jet pumps?
A: Jet pump efficiency typically ranges from 20% to 50%, depending on the specific design and operating conditions.

Q2: Why is efficiency important in jet pump selection?
A: Higher efficiency means less energy consumption for the same output, resulting in lower operating costs and better environmental performance.

Q3: What factors affect jet pump efficiency?
A: Nozzle design, diffuser geometry, fluid properties, operating pressures, and flow rates all significantly impact jet pump efficiency.

Q4: How can jet pump efficiency be improved?
A: Optimizing nozzle and diffuser design, proper sizing for the application, maintaining clean components, and operating at designed conditions can improve efficiency.

Q5: What are the limitations of this efficiency calculation?
A: This calculation assumes ideal conditions and may not account for all real-world losses such as friction, turbulence, and mechanical inefficiencies.
