3 cards from this section. Quick, good the night before a test.
Define momentum influx.
Think about direction of momentum.
What principle does Reynolds transport theorem relate?
Consider both volume and surface flows.
What does momentum influx refer to?
Think about fluid flow direction.
The Reynolds transport theorem relates momentum change to what?
Consider the definition of flux.
A jet with a mass flow rate of 2 kg/s impacts a plate at 15 m/s. Find the force exerted on the plate if the water exits the system at 5 m/s.
Use momentum change principles.
For a venturimeter with a large cross-section of 0.2 m² and a small cross-section of 0.05 m², calculate the velocity of the fluid if the flow is 40 L/s.
Utilize the area and flow rate relationships.
