Chapter 5. Introduction to Remote Sensing

5.6 Passive vs. Active Sensing Remote sensing systems which measure energy that is naturally available are called passive sensors. P assive sensors can only be used to detect energy when the naturally occurring energy is available. For all reflected energy, this can only take specular and diffuse reflection .

5.1 Shell-and-Tube Heat Exchangers

Example 5.2 Miniature Shell-and-Tube Heat Exchanger A miniature shell-and-tube heat exchanger is designed to cool engine oil in an engine with the engine coolant (50% ethylene glycol). The engine oil at a flow rate of 0.23 kg/s enters the exchanger at 120°C and leaves at 115°C. The 50% ethylene glycol at a rate of 0.47 kg/s enters at 90°C.

6.0 ENGINE COOLING SYSTEMS If this heat is not removed ...

heat input to the engine supplied by the fuel is absorbed by the engine cooling system. If this heat is not removed, engine internal temperatures would soon reach a point of component damage and engine failure. All commercial diesel engines use some form of cooling system to absorb this heat and transfer it to a heat absorbing medium
