The extraction of steam can either be controlled or uncontrolled.

In an uncontrolled extraction the pressure of the extracted steam will decrease with an increase in extraction flow from the

turbine.

In a controlled extraction the extraction pressure is kept constant as extraction flow is increased or decreased.

For a single throw, double pole switch, each section is wired to the individual items to be controlled. For a double throw double pole (220) set up, both hot wires are run through the switch.

### Why free turbine rotate in opposite direction?

Some CT based generators have 2 gas turbines, axially in-line, with a double ended generator/alternator centered between them. The Pratt &amp; Whitney model calls this a Twin-Pac. In this arrangement one Free Turbine requires a clockwise rotation, and the other Free Turbine requires a counter-clockwise rotation. Both may be coupled directly to the generator or via an over-running clutch for synchronous condenser operations.

### Describe what is meant by randomized controlled double-blind trials which is used to test drugs?

Randomized controlled double blind trials is when the drug tester and the GP/Scientist both dont know what the drug is and the randomized and controlled bit means that they also don't know what they are testing the drug for e.g certain diseases but they are under observation and they are only being given tiny dosages incase of any after effects.

### How vertical condensate extraction pump work?

CEP is a Multi stage vertical Centrifugal Pump having double suction impeller at 1st stage for higher efficiency and high flow rate .Pump operates at marginal difference between NASHa and NPSHr so pressure equalising line is provied at suction side .CEP suction is conected to Hotwell and above hotwell Vacuum is maintained as per turbine design. The purpose of CEP is transfer water to deaerator through LP heaters. Parag Agrawal 8102392375
