Fountain Performance Parameters

Our fountains are engineered using Bernoulli's principle of fluid dynamics. Key performance metrics include:

  • Water Flow Rate: 150-500 liters per minute depending on scale
  • Jet Height: Calculated using H = v²/2g where v is velocity and g is gravitational acceleration
  • Pressure Requirements: 1.5-3.5 bar operational pressure
  • Recirculation Rate: 98% water recycling efficiency
H = v² / 2g   |   P = ρgh   |   Q = Av

⚙️ Physics Principles

Marble Weight Calculations

Each marble component's weight is calculated using standard density parameters:

// Marble Density by Type (kg/m³) const MARBLE_DENSITY = { Carrara: 2710, Calacatta: 2690, Verde: 2720, Statuario: 2680 }; // Weight Formula function calculateWeight(volume_m3, marble_type) { return volume_m3 * MARBLE_DENSITY[marble_type]; }

Center of Gravity Analysis

For statues and balance-critical installations, we perform detailed center of gravity (CG) calculations to ensure structural stability:

  1. 3D scanning of raw marble block
  2. Finite element analysis (FEA) of proposed design
  3. CG location optimization through iterative simulation
  4. Pedestal design for CG alignment with vertical load axis
Engineering Note: Our statues achieve a minimum stability factor of 1.5, meaning they can withstand 150% of their own weight in lateral force before reaching tipping threshold.

Fountain Hydrology

Water behavior follows the continuity equation and Bernoulli's principle:

A₁v₁ = A₂v₂   |   P + ½ρv² + ρgh = constant
