Question

A stream has an average flow rate of 1.5 m^3/sec. How much water flows through this stream in 1 year?

a) 4.73 x 10^10 m^3
b) 1.5 x 10^10 m^3
c) 4.73 x 10^7 m^3
d) 1.5 x 10^7 m^3

Answer 1

The total volume of water flowing through a stream in one year, with an average flow rate of 1.5 m^3/sec, is 4.73 x 10^7 m^3. This is calculated by multiplying the flow rate by the number of seconds in a year.

Step-by-step explanation:

To calculate how much water flows through a stream with an average flow rate of 1.5 m3/sec in one year, follow these steps:

• First, find the number of seconds in one year: a year has 365 days (ignoring leap years), each day has 24 hours, each hour has 60 minutes, and each minute has 60 seconds. (365 days/year) × (24 hours/day) × (60 minutes/hour) × (60 seconds/minute) equals 31,536,000 seconds in a year.
• Then, multiply the average flow rate of the stream by the number of seconds in one year to get the total volume of water: (1.5 m3/sec) × (31,536,000 sec/year), which equals 47,304,000 m3 or 4.73 x 107 m3.

So, the total volume of water that flows through the stream in one year is 4.73 x 107 m3, which corresponds to answer (c).
