Agitator Design Calculation Xls Repack -

The Reynolds number identifies the flow regime (laminar, transitional, or turbulent) which dictates how power is consumed.

P = Np * ρ * N³ * D⁵

The primary calculation determines the motor power needed based on the fluid's physical properties and the chosen impeller. : : Power consumption (Watts). Npcap N sub p agitator design calculation xls repack

The dimensionless Power Number depends on the impeller type (e.g., turbine, propeller, anchor) and the presence of tank baffles. Npcap N sub p is typically constant for a given geometry. Viscous Fluids: An actual Npcap N sub p is calculated by applying a viscosity power factor ( fμf sub mu ) based on the NRecap N sub cap R e end-sub 3. Calculate Power Requirements The basic power requirement ( ) is derived from the power number and fluid properties. The Reynolds number identifies the flow regime (laminar,

Start with the process brief: fluid properties (density, viscosity), phase behavior (single-phase liquid, slurry, or gas-liquid dispersion), temperature, and vessel geometry. In the spreadsheet, these inputs live on a single, well-labeled sheet with dropdowns and inline notes — the human-friendly front door to the calculation engine.
