17.4. Ganga-Brahmaputra Confluence Example

Try these first

1. 1.

   Define mass conservation in your own words.

   Hint

   Think about it in terms of inflows and outflows.

2. 2.

   What is the formula for flow rate?

   Hint

   Remember the acronym WDV.

3. 3.

   What does the mass conservation principle state?

   • Mass can be created in a closed system
   • Mass is conserved in a closed system
   • Mass can be destroyed in a closed system

   Hint

   Focus on the definition of a closed system.

4. 4.

   True or False: The Reynolds Transport Theorem is not applicable to fluid flow at confluences.

   • True
   • False

   Hint

   Think about the significance of this theorem.

5. 5.

   Assume the inflow to the Padma River after the Ganga and Brahmaputra confluence is increased due to seasonal rains. How would you assess the impact this could have on the surrounding ecosystems?

   Hint

   Consider ecological changes due to water balance.

6. 6.

   If the average velocity of one of the inflow rivers increases due to a construction project upstream, how would it affect the calculations for water loss at the confluence?

   Hint

   Think about how velocity impacts flow rate.
