Challenge Problems
Push your limits with challenges.
Question 1
A system uses a pump to supply water through a 50 mm diameter pipe at a flow rate of 25 L/s. Given a roughness of 0.1 mm, calculate the head loss due to friction over a 100 m length of pipe.
💡 Hint: You will need to calculate the Reynolds number for determining flow regime first.
Question 2
Determine the efficiency of a turbine if it extracts 120 kW of mechanical energy from fluid flowing at a mass flow rate of 15 kg/s with an inlet pressure of 300 kPa and outlet pressure of 100 kPa.
💡 Hint: Make sure to consider the power generated at both pressures.
