4 cards from this section. Quick, good the night before a test.
What does the conservation of mass principle state?
Think about mass in terms of balance.
Define steady flow.
Consider what happens at a fixed point in the system.
What is the Reynolds Transport Theorem used for?
Focus on how it connects flow to conservation principles.
True or False: In unsteady flow, fluid properties at a point remain constant over time.
Consider the definition of unsteady.
A pipe has an inflow of 20 L/s and an outflow of 15 L/s. How would you calculate the change in water storage in the pipe over a time interval of 10 seconds?
Remember to consider both inflows and outflows.
In a system where water is pumped into a tank at 5 L/min and has an overflow outlet at 3 L/min, how long will it take to fill the tank from empty to a volume of 100 L?
Keep track of the net flow in relation to the total volume.
