Units of Calculations and Liquid Properties

Before delving into centrifugal pump calculations, it is essential to understand the units of measurements commonly used in pump engineering. The most common units include flow rate (m3/h or gpm), head (m or ft), power (kW or hp), and efficiency (%). Additionally, liquid properties such as viscosity, density, and temperature can significantly impact pump performance.

Centrifugal Pump Calculation Formulas

Several key formulas are used in centrifugal pump calculations to determine various parameters. Some of the essential formulas include:

1. Flow Rate (Q) Formula:

Q = (π * D^2 * N) / 4

2. Head (H) Formula:

H = (P2 - P1) / (ρ * g) + (V2^2 - V1^2) / (2 * g) + Z2 - Z1

3. Power (P) Formula:

P = (Q * ρ * g * H) / 1000

4. Efficiency (η) Formula:

η = (Pout / Pin) * 100%

Centrifugal Pump Size Chart

A centrifugal pump size chart is a valuable tool that helps in selecting the right pump size based on the required flow rate and head. The chart typically displays various pump sizes along with their corresponding performance curves, efficiency ratings, and power requirements. Engineers can use the size chart to match the pump specifications to the system requirements accurately.

Centrifugal Pump Coverage Chart

The centrifugal pump coverage chart provides information on the pump's operating range, including the maximum and minimum flow rates and heads. By referring to the coverage chart, engineers can ensure that the selected pump can meet the system's demand under varying operating conditions. It also helps in avoiding issues such as cavitation or overload.

Centrifugal Pump Design Calculations

Centrifugal pump design calculations involve determining the pump's hydraulic performance, structural integrity, and efficiency. Design calculations consider factors such as impeller size, shaft power, suction head, and discharge pressure to ensure optimal pump operation. Engineers use specialized software and mathematical models to perform detailed design calculations.
