Fire Demand Calculation in Iped Town
Population: 2 lakhs (200,000)
Fire Accident Frequency: Average of 1 fire accident per month
Fire Accident Duration: 4 hours
Step 1: Calculate the Fire Demand per Fire Accident
The fire demand is calculated using the National Board of Underwriters formula, which considers the population, fire accident frequency, and fire accident duration.
Fire Demand per Fire Accident = Population * Fire Accident Duration / 24
Fire Demand per Fire Accident = 200,000 * 4 / 24 = 33,333.33 lph (liters per hour)
Step 2: Calculate the Total Fire Demand
To calculate the total fire demand, we need to multiply the fire demand per fire accident by the fire accident frequency.
Total Fire Demand = Fire Demand per Fire Accident * Fire Accident Frequency
Total Fire Demand = 33,333.33 * 1 = 33,333.33 lph (liters per hour)
Step 3: Convert the Total Fire Demand to LPCD
LPCD stands for Liters per Capita per Day. To convert the total fire demand to LPCD, we need to divide the total fire demand by the population and then multiply it by 24.
LPCD = Total Fire Demand / Population * 24
LPCD = 33,333.33 / 200,000 * 24 = 4 lpcd
Conclusion:
The fire demand in Iped Town, considering a population of 2 lakhs and an average fire accident frequency of 1 per month lasting for 4 hours, is 4 liters per capita per day (lpcd). Therefore, option (B) 5 lpcd is the closest answer among the given options.
