Calculation of Peak Hourly Demand
Given: Average daily water consumption of a city = 24000 cum
To calculate peak hourly demand, we need to consider the maximum day, which means the day when the water consumption is at its peak. The peak hourly demand can be calculated using the following formula:
Peak Hourly Demand = Average daily water consumption / 24 hours
As per the given data, the average daily water consumption is 24000 cum. So, the peak hourly demand can be calculated as follows:
Peak Hourly Demand = 24000 / 24 = 1000 cum/hr
However, this is the peak hourly demand for an average day. We need to consider the maximum day, which means the day when the water consumption is at its peak. On such days, the peak hourly demand is usually higher than the average peak hourly demand.
As per industry standards, the peak hourly demand on the maximum day is usually 2.5 times the average peak hourly demand. So, the peak hourly demand on the maximum day can be calculated as follows:
Peak Hourly Demand (Maximum Day) = 2.5 x 1000 = 2500 cum/hr
Therefore, the correct answer is option D, i.e., 2700 cum/hr.

Avg. water consumption per hour = 24000/24 = 1000 cum/hr
then,peak hourly demand =2.7×Avg. water consumption = 2.7 × 1000 = 2700 cum/hr
