A centrifugal pump is rated for 500 USGPM at 100 ft of head. Using the Affinity Laws, what will the new flow be if the pump speed is increased from 1750 RPM to 2000 RPM? a) 437 USGPM b) 571 USGPM c) 653 USGPM d) 500 USGPM
Common question: "In a reaction turbine, the degree of reaction is 50%. What does this imply?" power engineering 3b1 exam questions
A centrifugal pump operates at 1800 RPM and delivers a flow rate of 500 L/s against a head of 30 meters. If the pump speed is reduced to 1200 RPM, what is the new flow rate?
A 10-stage steam turbine uses pressure compounding. What is the primary advantage of this design over a single-stage impulse turbine? a) Higher exhaust velocity b) Lower rotational speed for the same pressure drop c) Elimination of the need for a governor d) Higher steam wetness at exhaust Calculating velocity, acceleration, and centrifugal force

When analyzing past , certain topics appear frequently. These are the "high-value" areas you must master.
Calculating tensile, compressive, and shear stress.
Typically, the exam consists of multiple-choice questions (MCQs). The questions are designed to test three levels of cognition:
