Question 1.
What is conservation of momentum?
Show hintHide hint
Think about mass and velocity.
Question 2.
Define incompressible flow.
Show hintHide hint
Consider fluid density during flow.
3Question 3.
What is conservation of momentum?
- The principle of mass conservation
- The principle that a closed system's total momentum remains constant
- The principle of energy conservation
Show hintHide hint
It involves velocity and mass.
4Question 4.
In steady flow, fluid properties change with time.
- True
- False
Show hintHide hint
Think about how conditions remain the same.
Question 5.
Given a fluid flow system with varying diameters at inlets and outlets, derive the momentum conservation equations and solve for the outlet velocity, taking into account frictional losses.
Show hintHide hint
Start by balancing the inflow and outflow rates.
Question 6.
A hydropower project utilizes a river with steep gradients. Assess the momentum changes as the water is diverted for turbine use, calculating energy outputs based on flow rates and density variations.
Show hintHide hint
Consider how momentum and energy conservation will be applied in this scenario.
