Precast concrete utility vault configurator: dimensions and joint profile drive concrete volume, weight and pricing — the top slab and its access opening reconfigure live in 3D.
Shell and head thickness to ASME VIII-1 (UG-27, UG-32), the plate to buy, the MAWP it gives you and the hydrotest pressure — with the formulas shown.
Working stress and factor of safety against yield for a loaded member, with a pass/warn/fail band and the allowable load for a target factor.
Friction loss for water in a pipe — velocity, Reynolds number, Swamee–Jain friction factor, Darcy–Weisbach head loss in feet and psi.
Series and parallel totals for any list of resistors — add or remove resistors and both equivalents update live.
