Process Instrumentation Methods

Safety Valve Sizing

Safety valve sizing follows ASME Boiler and Pressure Vessel Code Section VIII requirements:

A = W / (K × Kb × Kc × P × √(M / T))

Where A is the required discharge area, W is the required relief rate, K is the coefficient of discharge, Kb is the backpressure correction factor, Kc is the combination correction factor, P is the set pressure, M is the molecular weight, and T is the absolute temperature.

Orifice Meter Calculations

Orifice meter flow calculations follow ISO 5167 standards:

Q = C × ε × π/4 × d² × √(2 × ΔP / ρ)

Where Q is the volumetric flow rate, C is the discharge coefficient, ε is the expansibility factor, d is the orifice diameter, ΔP is the differential pressure, and ρ is the fluid density.
