Flowrate Lb/Hr (Drop down for distance units - Can't be zero or less)

Upstream Valve Inlet Pressure Psia (Drop down for pressure units - Can't be less than atmospheric pressure)

Upstream Valve Inlet Temperature Deg F (Drop down for temperature units - Can be positive and negative - cannot be less than 273.15 Kelvin)

Upstream Valve Outlet Pressure Psia (9999 for don't know - Drop down for pressure units - cant be more than valve inlet pressure, cant be less than 0 Psia)

Upstream Valve Outlet Temperature Deg F (9999 for dont know - Drop down for temperature units - Cant be more than valve inlet temperature - cant be less than minus 0 Kelvin)

Valve Type

Nominal Valve Size (Zero if unknown - Drop down for pressure units - cannot be more than valve outlet pressure minus silencer inlet pressure)

Valve Cv - Fully open USGpm/min (Zero if unknown, cant be less than zero)

Valve Opening characteristic - If Known (default to Linear)

Valve Make - If Known (Text entry)

Valve Model - If Known (Text entry)

Pressure Drop Across Silencer Psi (Zero if unknown - Diffuser required if greater than 0.5 Psi)

Diffuser fitted to silencer

Pressure Drop In Inlet Pipe Psi(Zero if unknown - Drop down for pressure units - cannot be more than valve outlet pressure minus silencer inlet pressure)

Pressure At Silencer Inlet Psia(Zero if unknown - Drop down for pressure units - cannot be less than the silencer outlet pressure - cannot be more than the valve outlet pressure or the valve outlet pressure minus the pressure drop in the inlet pipe)

Pressure At Silencer Outlet Psia (Zero if unknown, will take site altitude pressure - Drop down for pressure units - cannot be less than the site altitude related pressure or the silencer inlet pressure - can be more than altitude pressure if outlet pipe/stack connected)

Pipeline Length between valve and silencer (If known) Metres (Drop down for distance units - Zero for unknown)

Pipeline Nominal Diameter (Drop down for allowable pipe sizes)

Pipeline Schedule Thickness (Drop down for pipe schedules)

Pipeline Material Inches (Drop down for pipe materials)

Guaranteed Silenced Noise Level (Default 85)

Design Silenced Noise Level - Below Guarantee Level

Horizontal distance to guarantee point Metres (Input number, not less than 1metres - drop down for distance units - default = 1.0 )

Vertical distance to guarantee point Metres (Input number, can be less than zero - drop down for distance units - default = 0.0)
