A series RLC circuit consists of a 100 W resistor, a 0.15 H inductor, and a 30 µF capacitor. It is attached to a 120 V/60 Hz power line (the voltage 120V is the root mean square value). What are a. The emf εrms

b. The phase angle ϕ

c. The average power loss

A large dynamometer operates a pump that circulates a viscous fluid through a restrictive fluid circuit. ... Under Steady Operating Conditions, Heat Loss From The Fluid Is Measured As 150 KW When The Shaft Is Rotating At 1000 Rpm, And 275 KW When The Shaft Speed Increases To 2000 Rpm. The Pump Efficiency Varies ...
