Water Pressure Calculator

How to use it

1. Convert height to pressure: 15m = 1.5 bar (10m = 1 bar)
2. Calculate friction losses: 15m x 0.15 = 2.25m additional head
3. Total pressure: 15m + 2.25m = 17.25m = 1.725 bar
4. Estimate pump power based on required flow rate

Common mistakes

• ⚠️ Not Consider pérdidas per fricción in tuberías largas
• ⚠️ Dimensionar bomba solo per height (ignorar flow rate necessary)
• ⚠️ Not prever vaso of expansión to evitar arranques frecuentes

Worked example

Calculate water pressure for a 15m column height with 15% friction losses.

For {height_m}m height with {perdidas_carga_pct}% losses: {bar_bruto} bar gross, {bar_neto} bar net, {psi} PSI, {kpa} kPa.
