Introduction

L.P.G (Liquefied Petroleum Gas) is a common household energy source in many parts of the world. It is often used for cooking and heating. To understand the energy consumption pattern of a family, we can calculate the average energy consumed per day. In this article, we will demonstrate how to calculate the average energy consumed per day when a family consumes 12 kg of L.P.G in 30 days.

Calculating the Total Energy

The first step in determining the average daily energy consumption is to calculate the total energy consumed over the given period of time. This can be done using the following formula:

[ text{Total Energy} text{mass of L.P.G} times text{calorific value} ]

Given the calorific value of L.P.G as 50 kJ/kg and the mass of L.P.G consumed as 12 kg, we can substitute the values into the formula:

[ text{Total Energy} 12 , text{kg} times 50 , text{kJ/kg} 600 , text{kJ} ]

Calculating the Average Daily Energy Consumption

To find the average energy consumed per day, we need to divide the total energy by the number of days:

[ text{Average Energy per Day} frac{text{Total Energy}}{text{Number of Days}} ]

Substituting the values we have:

[ text{Average Energy per Day} frac{600 , text{kJ}}{30 , text{days}} 20 , text{kJ/day} ]

Therefore, the average energy consumed per day by the family is 20 kJ/day.

Understanding the Calorific Value of L.P.G

The calorific value of L.P.G is the amount of energy released when a unit quantity of L.P.G is completely burned. For L.P.G, the calorific value is typically given as 50 kJ/kg. This means that each kilogram of L.P.G releases 50 kJ of energy.

Application in Daily Life

Understanding the average energy consumption of L.P.G in daily life is crucial for several reasons. It helps in:

Estimating monthly energy bills. Maintaining efficiency in cooking and heating practices. Planning for future L.P.G purchases and storage. Reducing energy waste and conserving resources.

By knowing the average energy consumed per day, families can better manage their energy usage and make informed decisions regarding their L.P.G consumption.

Conclusion

Through the calculation of the total energy consumed and the average energy consumed per day, we have demonstrated the importance of understanding L.P.G's calorific value and energy consumption in daily life. This knowledge not only aids in managing household expenses but also in promoting sustainable energy practices.
