Torispherical Tank is a lightweight, precision-focused iOS app built for anyone who needs fast, reliable calculations on torispherical vessels—whether you’re a student learning geometry, an engineer sizing process equipment, or a technician checking specs in the field.

Key Features & Functionality

Volume Calculator
Compute the internal volume of a torispherical tank by entering crown diameter, knuckle radius, and overall length
Switch seamlessly between Imperial (ft³, in) and Metric (m³, mm) units
Instant results with step-by-step breakdown of the formulas used

Thermal Ballast Calculator
Determine ballast (holding) time based on:
Heat duty (BTU/hr)
Temperature differential (ΔT) between inlet and outlet fluids
Or, flip the calculation: provide a fixed volume and ΔT to find required heat duty or time
