An electric shower operates at a power of 3,600 W. What is the monthly energy consumption, in kWh, if it is used for 15 minutes daily? Consider a month with 30 days.
Question
Answer:
To calculate the monthly energy consumption of the electric shower, you can follow these steps:
1. Calculate the daily energy consumption:
The power of the electric shower is 3,600 watts (3.6 kW), and it is used for 15 minutes each day.
Energy consumption per day = Power (kW) Γ Time (hours)
Energy consumption per day = 3.6 kW Γ (15 minutes / 60 minutes) = 0.9 kWh
2. Calculate the monthly energy consumption:
Since there are 30 days in the month, you can multiply the daily energy consumption by 30 to get the monthly energy consumption.
Monthly energy consumption = Daily energy consumption Γ Number of days
Monthly energy consumption = 0.9 kWh/day Γ 30 days = 27 kWh
So, the monthly energy consumption of the electric shower, if used for 15 minutes daily for 30 days, is 27 kWh.
