Hook-ups are basically of two types Process Hook-Ups and
Pneumatic Hook-Ups. hook ups give complete information
required for installation of a particular instruments which
indicates cable entries, support details, connection sizes.
It clearly defines the instrumentation scope for
installation and helps in identifying the materials and
accesories required during installation
Process Hook-Ups covers all field instruments installed on
pipelines/vessels and other process equipments and
Pneumatic Hook-ups covers all instruments which require
instrument air to operate

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
