• Application (Vent, Blow down, Relief) • Fluid Composition (Steam, Gas, Air) • Molecular Weight or Specific Gravity • Process conditions upstream of valve and units (lb/hr, SCFM, ACFM), Temperature Pressure (P 1) • Atmospheric pressure ( P a ) and temperature (T 2) if known. • Line size between valve and silencer • Line size from silencer discharge • Unsilenced octave band noise levels, • Attenuation required (silencer performance) • Allowable pressure drop
