## What is Agitator Mixer Speed Calc?

Need to size an agitator for a mixing tank but tired of hand-calculating RPM from tip speed? Wondering if your flow regime is laminar or turbulent? This app eliminates guesswork for impeller selection and motor sizing.

Enter tank diameter, impeller size and type (propeller, paddle, turbine, anchor), fluid properties (viscosity and density), and target tip speed. Instantly calculates RPM, Reynolds number, flow regime (laminar/transitional/turbulent), power requirement in HP, and D/T ratio.

IMPELLER TYPES:
- Propeller (marine type)
- Paddle (flat blade)
- Turbine (Rushton)
- Anchor (slow speed)

KEY FEATURES:
- Reynolds number with flow regime classification
- Power draw calculation with Np correlation
- Tip speed to RPM conversion
- D/T ratio check
- Works completely offline
- No account or login required

Built for chemical engineers, process engineers, and plant operators who need quick agitator sizing on the job.
