What is the equivalent flow rate of 1 million gallons per day in cubic feet per second (cfs)?

What is the equivalent flow rate of 1 million gallons per day in cubic feet per second (cfs)?

• A. 0.75 cfs
• B. 1.00 cfs
• C. 1.55 cfs
• D. 2.00 cfs

Answer: (C)

To convert flow rates from gallons per day to cubic feet per second, it's essential to use the appropriate conversion factors. Start by recognizing that there are 7.48 gallons in a cubic foot. Therefore, to convert from gallons to cubic feet, divide the number of gallons by 7.48. The conversion also involves time, so since there are 86400 seconds in a day (24 hours x 60 minutes x 60 seconds), the conversion proceeds as follows: 1 million gallons per day can be expressed mathematically as: 1,000,000 gallons/day * (1 cubic foot / 7.48 gallons) * (1 day / 86400 seconds). Calculating this step-by-step: 1. Convert gallons to cubic feet: \( 1,000,000 \text{ gallons} \div 7.48 \text{ gallons/cubic foot} \approx 133,686.5 \text{ cubic feet} \). 2. Now convert cubic feet per day into cubic feet per second: \( 133,686.5 \text{ cubic feet} \div 86400 \text{ seconds/day} \approx 1.55 \text{ cfs} \). This indicates

2. Now convert cubic feet per day into cubic feet per second:

( 133,686.5 \text{ cubic feet} \div 86400 \text{ seconds/day} \approx 1.55 \text{ cfs} ).
