Question
Chapter 45, Problem 1RQ
To determine
The name of synchronous motor when it is operated without the load and used for power factor correction.
Expert Solution & Answer
Explanation of Solution
Consider that the synchronous motor operate at the synchronous speed and the produce a leading power factor.
The case when the synchronous motor is operated without load to correct the power factor then the synchronous motor is known as the synchronous condenser.
Thus, the machine is called the synchronous speed.

The regenerator has an effectiveness of 79 percent, and the air enters the turbine at 1400 K. Assume constant specific heats for air at room temperature. The properties of air at room temperature are cp = 1.005 kJ/kg·K and k = 1.4. For a turbine efficiency of 90 percent, determine the amount of heat transfer in the regenerator.
