FUN WITH HEAT EXCHANGER

Figure shows ___________heat exchanger.

• Double-pipe

• Multipass

• Cross-flow

• None of above

Choose two(2) types of flow arrangement possible in double-pipe heat exchanger.

• Parallel flow

• Counter flow

• Multipass

• Cross-flow

Choose types of heat exchanger that we had learned in chapter 4.

• Double pipe

• Compact

• Shell and tube

• Plat and frame

•The simplest type of heat exchanger

•One fluid flows through the smaller pipe while the other fluid flows through the annular space between the two

pipes.

Statements above best describe what type of heat exchanger?

• Plate and frame

• Shell and tube

• Double pipe

• Compact

•Large heat transfer surface area per unit volume.

•Area density B ─ heat transfer surface of a heat exchanger to volume ratio.

• This type of heat exchanger has B >700 m2/m3.

Statements above best described what type of heat exchanger?

• Plate and frame

• Shell and tube

• Compact

• Double pipe

Choose example/s of compact heat exchanger.

• Car radiator

• Human lung

• Glass-ceramic gas turbine

• The regenerator of a Stirling engine

Compact heat exchanger typically has ________configuration where the two fluids move __________ to each other.

• counter flow,opposite

• cross flow,parallel

• cross flow,perpendicular

• counter flow,perpendicular

Figure represents compact heat exchanger which typically available in cross-flow configuration.The cross-flow configuration is further classified as A and B.

Identify A and B.

• A=unmixed,B=partially mixed

• A=unmixed,B=mixed

• A=mixed,B=unmixed

• A=partially mixed,B=partially unmixed

This figure represents what type of heat exchanger?

• Double pipe

• Plate and frame

• Shell and tube

• Compact

•Consists of a series of plates with corrugated flat flow passages.

•The hot and cold fluids flow in alternate passages

•Well suited for liquid-to-liquid heat exchange applications, provided that

the hot and cold fluid

streams are at about the

same pressure.
