Chapter 49, Problem 1RQ
How does the compressor lubrication system differ for reciprocating and centrifugal compressors?
Expert Solution & Answer
To determine
Difference in lubrication system of reciprocating and centrifugal compressor.
Answer to Problem 1RQ
Difference in lubrication system of reciprocating and centrifugal compressors has explained below.
Explanation of Solution
Compressor is a device which is used to compress the fluid.
Lubrication is required to reduce the heat and friction.
The centrifugal compressor consists of a separate pump, filter, cooler, oil lines and oil reservoir. The lubrication oil pumped from the reservoir to the various parts of the engine.
The reciprocating compressor consists of a small pump system which is driven by compressor crankshaft.
In reciprocating compressor, the lubricating oil pump is driven by compressor shaft whereas in centrifugal compressor, the oil pump is driven by separate motor.
Reciprocating compressor does not have separate sump for the oil, but centrifugal compressor has separate oil sump.

A heavy car plunges into a lake during an accident and lands at the bottom of the lake
on its wheels as shown in figure. The door is 1.2 m high and I m wide, and the top edge of
the door is 8 m below the free surface of the water. Determine the hydrostatic force on the
door if it is located at the center of the door, and discuss if the driver can open the door, if
not; suggest a way for him to open it. Assume a strong person can lift 100 kg, the passenger
cabin is well-sealed so that no water leaks inside. The door can be approximated as a
vertical rectangular plate.
