Pendahuluan Mekanika Fluida terjadi pada sekitar kita : �Aliran darah melalui pembuluh darah �Kapal berlayar di sungai, �Pesawat terbang di angkasa �Udara bergerak melewati wind tunnel �Udara dimampatkan pada kompresor �Uap berexpansi melalui bilah turbin �Bendungan yang menahan air �Udara dipanaskan / didinginkan di rumah �Komputer memerlukan udara untuk mendinginkan komponen
Hydrostatics - Application Hydro - water. Static - isn't moving. Application : 1. Water Dam – mass 2. Water Tank, infus – height 3. Toilet 4. Boats 5. Lifesavers
Archimedes - Application Archimedes' principle the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces �Submarine �Hot-air balloon �Hydrometer �Ship �Fishes
Piping Structural steel pipe racks typically support pipes, power cables and instrument cable trays in petrochemical, chemical and power plants. Occasionally, pipe racks may also support mechanical equipment, vessels and valve access platforms. Main pipe racks generally transfer material between equipment and storage or utility areas. Storage racks found in warehouses are not pipe racks, even if they store lengths of pipe.

Dimensi, Unit dan Satuan
Dimensi, Unit dan Satuan Stress Vector : Force Vector divided by the area upon which it acts Normal Stress : normal to the area Shear Stress : tangent to the area Shear Stress : gas , ketchup � Pressure � Pgage : pressure relative to Temperature atmospheric pressure � Pabsolute : zero in the volume the is void of molecules, an ideal vacuum � Patmosphere the atmospheric pressure at the location where the pressure measurement is made -> elevation = 100 kpa � Vacuum / negative pressure (-30 kpa = 70 kpa absolute or vacuum 30 kpa)
