Challenge Problems
Push your limits with challenges.
Question 1
An impulse turbine has a mass flow rate of 5 kg/s, with whirl components of velocity: Vw1 = 20 m/s and Vw2 = 15 m/s. Calculate the work output using the equation W = m(Vw1 + Vw2)u. Assume blade speed u = 10 m/s.
💡 Hint: Make sure to sum the whirl components before multiplying by mass flow rate and blade speed.
Question 2
Discuss the impact of mechanical complexity introduced by velocity compounding. How might this affect maintenance and performance of turbines in an industrial setting?
💡 Hint: Think about how more components could lead to more points of failure.
