Answer the following statement(s) true (T) or false (F)

1. The winding of a three-phase, squirrel-cage induction motor is made of formed coils that are connected to give three single-phase windings spaced 60 electrical degrees apart.
2. Some types of squirrel-cage induction motors are smaller than others and have aluminum end rings that are cast in one piece.
3. At start-up, all of the resistance of the wye-connected speed controller is inserted in the rotor circuit.
4. The stator leads of a three-phase, wound-rotor induction motor are marked M1, M2, and M3.
5. The wound-rotor motor and the squirrel-cage motor have the same percent efficiency, power factor, percent slip, speed, and torque characteristics.

An insulated steam turbine produces 67,000 hp of power. Steam enters the turbine at 2000 psia and 1000°F, with a velocity of 400 ft/s, through a duct with a cross-sectional area of 0.20 ft2. The steam exits with a velocity of 30 ft/s, at a temperature of 420°F. Determine the exit pressure and, if applicable, the exit quality of the steam.

Given: P1 = 2000 psia; T1 = 1000°F; V1 = 400 ft/s; A1 = 0.20 ft2; T2 = 420oF ; V2 = 30 ft/s; W?=67000 hp=47,365 Btu/s; Steam Assume: Q? = 0 (insulated) Also, for a turbine, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?vPE = 0 What will be an ideal response?
