Question 1
What is the primary factor determining thrust in a fluid jet?
- Density
- Velocity
- Volume
- Pressure
💡 Hint: Think about what happens to the mass flow as fluid speeds up.
Question 2
True or False: In incompressible flow, the speed of the fluid can change without affecting density.
- True
- False
💡 Hint: Consider how liquids behave under pressure.

Question 1
A spacecraft is moving at 900 m/s, and a solid fuel engine expels gases at 70 kg/s. If the gases exit with a speed of 3000 m/s, calculate the thrust generated by the rocket engine.
💡 Hint: Break down the components to calculate thrust correctly.
Question 2
If a water jet of 0.01 m² area strikes a plate at 25 m/s, and water density is 1000 kg/m³, determine the force applied to the plate due to the water jet.
💡 Hint: Use mass flow rate to derive thrust.
