Country-neutral calculator for Orifis and Tank Bosalma Preliminary Analysis - Dere Gecisi Tank Bosalma Suresi.
Use consistent units and the requested inputs.
Use the main result and breakdowns as a planning estimate.
For regulated topics, verify current local rules before acting.
Tank drawdown to zero under changing head, constant horizontal tank area At: t=2 At sqrt(H)/(Cd A sqrt(2g))/60 minutes. This is NOT constant-head Q=Cd A sqrt(2gH) applied over full period.
Inputs: At=12 m², Cd=0.62, d=80 mm, H=3 m (evaluate using the calculator above).
Tank drawdown to zero under changing head, constant horizontal tank area At: t=2 At sqrt(H)/(Cd A sqrt(2g))/60 minutes. This is NOT constant-head Q=Cd A sqrt(2gH) applied over full period.
Incompressible quasi-steady free discharge; effective head is measured to orifice centreline for free flow or differential head for submerged flow. Coefficient Cd depends on edge/approach/submergence and must be calibrated. An ideal speed formula does not predict actual exit flow without contraction/losses.
Review the values and units used by this calculator before calculating.
