Farm Tools vs Pipe Sizer

Farm Tools Farm Tools is the essential calculator app for farmers, agronomists, and anyone who works the land. Built for speed and simplicity, it puts the math you do every day right in your pocket. Estimated Yield Estimate corn yield before harvest using the ear-count method. Enter row spacing and kernel counts from sample ears and get an instant bushels-per-acre estimate. Bin Capacity Calculate grain bin storage in bushels. Enter the bin diameter and wall height and the app accounts for the cone at the base for an accurate total. Sprayer Calculators Dial in your application rates on the fly. Calculate injection rate, volume required, and gallons per hour — enter any two known values and get the third instantly. Ohm's Law Solve voltage, current, resistance, and wattage calculations in the field. Enter any two values and the other two are solved automatically — handy for electric fencing, sensors, and equipment wiring. Pulley / Drive Calculate pulley RPM and sheave sizes for belt-driven equipment. Enter any three values and the unknown is solved for you. Tank Volume Find the volume of round or square tanks in gallons. Supports cylinders, horizontal tanks, and rectangular containers. Field Coverage Calculate field area in acres from length and width. Great for estimating product needed and tracking coverage. GPS Location View your current coordinates and position on a map. Useful for recording field locations, fence corners, and equipment positions. Yield Calculator A quick general-purpose yield and harvest calculator. Clean, fast, and works offline. No subscriptions. No ads.

PipeSizer helps you quickly choose the right pipe diameter for water systems — for both pressure and gravity flow. PRESSURE PIPE SIZING • Size pipes from a target flow rate. • Set your maximum friction rate and velocity limits. • Calculations based on the Hazen-Williams equation. GRAVITY PIPE SIZING • Size pipes from a target flow rate. • Evaluate flow capacity and velocity under gravity conditions. • Calculations based on the Manning equation. KEY FEATURES • Automatic recommended pipe size based on your limits. • Multiple pipe materials with built-in coefficients (more added over time). • Works in both SI and Imperial (I-P) units. • Designed for engineers, plumbers, and irrigation/drainage design workflows. Feedback is welcome — it directly shapes upcoming updates.
