In axial flow compressors, compression occurs: In both stationary and rotating blades
In a centrifugal compressor, the amount of velocity to pressure conversion through
the impeller
is a function of the: Degree of curvature of the impeller blades
Positive displacement compressor types include:
1. Sliding vane

The advantages of using a reheater in a gas turbine cycle are:
1. More air can be compressed
2. A small combustor may be used
3. Less air will have to be compressed in order to do the same amount of work
4. The thermal efficiency of the cycle will be improved 3, 4
The _____ control method can be used when a compressor is driven by a steam
engine, a
turbine, or an internal combustion engine. Variable speed
When first starting a turbine, the purpose of admitting only enough steam to turn the
turbine
over very slowly is to: Allow the operator time to listen for rubbing or other unusual
noises
If _____ is used then the cylinder is constructed with integral cast fins which provide
increased
radiating area. Air cooling
The purpose of the push rod is to operate the: Rocker arm
The emergency line of refrigeration system shall be provided with a: Diffuser at its
upper
end that shall be placed above the roof
, Q: A mechanical overspeed trip is designed to _____ in the event of an overspeed
condition. Shut off the turbine's steam supply An electronic-hydraulic governor
system uses: A separate fluid power unit for high pressure oil In the basic
absorbing system the dividing line between the high side and the low side is the:
Aqua pump and the expansion valve The low-side float valve is controlled by: A
float connected to/or in the evaporator Reheat is accomplished in a gas turbine
by: Heating the gases between the HP and LP turbine Air flow to each individual
burner for a fired heater is controlled by a/an: Air register How does air enter a
condenser?
Answer:
1. Air pumps 2. Gland leaks 3. Carried in with steam 4. Leaky flanges 2, 3, 4 The
upper pH limit for wastewater is: 8.5 The operating principles of the diesel engine
include: 1. The charge drawn into the cylinder is air only. 2. The fuel is injected at
the beginning of the compression stroke.
