Challenge Problems
Push your limits with challenges.
Question 1
In a closed hydraulic system, if a pump increases the pressure from 2 bar to 5 bar and the flow rate is 10 L/min, what is the mechanical power input required for this system?
💡 Hint: Use the formula relating power to flow rate and pressure head.
Question 2
If the energy efficiency of a hydraulic system is calculated to be 75%, and the input energy is 400 J, how much energy is lost?
💡 Hint: Knowing the efficiency can help calculate the output energy, hence the lost energy.
