₹0.0

Question: A river\'s flow rate is measured at 1500 liters per second. How many cubic meters of water does it flow in an hour? (2021)

Options:

Correct Answer: 3600 m³

Exam Year: 2021

Solution:

Flow in an hour = 1500 liters/second × 3600 seconds = 5400000 liters = 5400 m³.

A river's flow rate is measured at 1500 liters per second. How many cubic meters of water does it flow in an hour? (2021)

Step 1: Understand that the flow rate of the river is 1500 liters per second.
Step 2: Calculate how many seconds are in one hour. There are 60 seconds in a minute and 60 minutes in an hour, so 60 seconds/minute × 60 minutes/hour = 3600 seconds/hour.
Step 3: Multiply the flow rate by the number of seconds in an hour to find the total flow in liters. So, 1500 liters/second × 3600 seconds = 5400000 liters.
Step 4: Convert liters to cubic meters. Since 1 cubic meter is equal to 1000 liters, divide the total liters by 1000. So, 5400000 liters ÷ 1000 = 5400 cubic meters.

Flow Rate Conversion – Understanding how to convert flow rate from liters per second to cubic meters per hour.
Time Conversion – Calculating the total time in seconds for one hour to apply to the flow rate.
Volume Measurement – Recognizing the relationship between liters and cubic meters (1 m³ = 1000 liters).
