Consider for example the flow of gas through a pipeline. If the states and thermodynamic
properties of the gas entering and leaving the pipeline are known, then application of the first
law establishes the magnitude of the energy exchange with the surroundings of the pipeline.
The mechanism of the process, the details of flow, and the state path actually followed by
the fluid between entrance and exit are not pertinent to this calculation. On the other hand, if
one has only incomplete knowledge of the initial or final state of the gas, then more detailed
information about the process is needed before any calculations are made. For example, the exit
pressure of the gas may not be specified. In this case, one must apply the momentum principle
of fluid mechanics, and this requires an empirical or theoretical expression for the shear stress
at the pipe wall.

Pertimbangkan misalnya aliran gas melalui pipa. Jika negara bagian dan termodinamika
sifat gas memasuki dan meninggalkan pipa diketahui, maka aplikasi pertama
hukum menetapkan besarnya pertukaran energi dengan lingkungan pipa.
Mekanisme proses, rincian aliran, dan jalan negara benar-benar diikuti oleh
cairan antara pintu masuk dan keluar tidak berkaitan dengan perhitungan ini. Di sisi lain, jika
seseorang memiliki hanya pengetahuan yang tidak lengkap dari keadaan awal atau akhir dari gas, maka lebih rinci
informasi tentang proses yang diperlukan sebelum perhitungan dibuat. Misalnya, keluar
tekanan gas tidak dapat ditentukan. Dalam hal ini, kita harus menerapkan prinsip momentum
mekanika fluida, dan ini membutuhkan ekspresi empiris atau teoritis untuk tegangan geser
pada dinding pipa.
