Axial flow (e.g., hydrofoils, marine propellers) or radial flow (e.g., Rushton turbines, pitch blade turbines). 2. Step-by-Step Process Design Calculations Step 1: Calculate the Reynolds Number (

The power consumption of an impeller depends heavily on its geometry and the fluid flow regime. The Power Number ( Npcap N sub p

As in all kinds of process equipment, agitators must be correctly sized to deliver the necessary process function while maximizing return on investment and minimizing total energy cost. agitator design calculation pdf download verified

For turbulent flow, the power (P) required for agitation is accurately given by the following equation:

A verified PDF should include:

= Maximum static deflection of the shaft under its own weight and the weight of the impeller. Operating speed (

An agitator shaft behaves as a rotating beam subject to combined torsion, bending, and axial loads. Mechanical validation prevents catastrophic structural failures. Torque Calculation Axial flow (e

For laminar flow: ( P = K_p \cdot \mu \cdot N^2 \cdot D^3 ), where ( K_p ) = power constant (e.g., 65 for anchor).

Re=ρ⋅N⋅D2μcap R e equals the fraction with numerator rho center dot cap N center dot cap D squared and denominator mu end-fraction = Fluid density ( kg/m3kg/m cubed = Agitator rotational speed ( rev/srev/s = Impeller diameter ( = Dynamic viscosity ( Flow Regimes: Transitional: Turbulent: Step 2: Determine the Power Number ( Npcap N sub p The Power Number ( Npcap N sub p
