HIRA- Hazard Identification & Risk Analysis.
HAZOP-Hazard & Operability study.
The main difference lies in the name itself. HIRA represents a collective term which comprises of all the different activities involved in identifying hazards & evaluating risks at facilities to make certain that the risks to employees, equipments , public & environment are within the organization risk tolerance limit. Generally it consists of 3 main questions: Hazard, Consequences & Likelihood.
While HAZOP is a part of HIRA. It consists of what if analysis, check lists & failure mode & effective analysis.

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
