Total Liters: Water Meter Reading (m³) × 1000
Number of Fillings: Total Liters / Tank Volume (94 L)
Total Operational Hours: Number of Fillings × Estimated Filling Time (0.139 hours)
Energy Consumption (kWh): Pump Power (1.1 kW) × Total Operational Hours
Total Electricity Cost (Pesos): Energy Consumption (kWh) × Electricity Rate (Pesos per kWh)
Pump Power (kW): The power rating of the water pump is set to 1.1 kW (1 HP).
Tank Volume (Liters): The capacity of the water tank is 94 liters.
Estimated Filling Time (Hours): The time it takes to fill the tank from 0 to full at the specified pressure, calculated as 8 minutes and 20 seconds (0.139 hours).
Step-by-Step Calculation:
1. Total Liters: Convert the water meter reading from cubic meters (m³) to liters (L).
Example: If Water Meter Reading = 10 m³, then Total Liters = 10 × 1000 = 10,000 L.
2. Number of Fillings: Divide the total liters by the tank volume to get the number of times the pump needs to fill the tank.
Example: If Total Liters = 10,000 L and Tank Volume = 94 L, then Number of Fillings = 10,000 / 94 ≈ 106.38.
3. Total Operational Hours: Multiply the number of fillings by the estimated filling time to get the total operational time of the pump.
Example: If Number of Fillings = 106.38 and Filling Time = 0.139 hours, then Total Operational Hours = 106.38 × 0.139 ≈ 14.78 hours.
4. Energy Consumption (kWh): Multiply the pump power by the total operational hours to calculate the total energy consumed.
Example: If Pump Power = 1.1 kW and Total Operational Hours = 14.78 hours, then Energy Consumption = 1.1 × 14.78 ≈ 16.26 kWh.
5. Total Electricity Cost (Pesos): Multiply the energy consumption by the electricity rate to calculate the total cost.
Example: If Energy Consumption = 16.26 kWh and Electricity Rate = 12 Pesos/kWh, then Total Cost = 16.26 × 12 ≈ 195.12 Pesos.
