Base Failure Rate
|
Real (Failures/Million Hours)
|
The base or manufacturer-supplied failure rate. Generally, this field is left at #.# so that the failure rate is calculated based on the values entered for other parameters. If you enter a value for this parameter, this value is used in place of a calculated failure rate.
|
|
Radius - Inside
|
Real (in). Used in Cdp and Ccf calculations.
|
The inside radius of the filter in inches, which is used to determine the Cdp factor.
|
|
Radius - Outside
|
Real (in). Used in Cdp and Ccf calculations.
|
The outside radius of the filter in inches, which is used to determine the Cdp factor.
|
|
Design Pressure - Inside
|
Real. Used in Cdp calculation.
|
The rated pressure on the inside of the filter, which is used to determine the Cdp factor.
|
|
Design Pressure - Outside
|
Real. Used in Cdp calculation.
|
The rated pressure on the outside of the filter, which is used to determine the Cdp factor.
|
|
Radius at Max Stress
|
Real (in). Used in Cdp calculation.
|
The radius of the filter in inches at the point of maximum stress. For filters that flow from outside to inside (most filters), this is equal to the outside radius.
|
|
Off Design Pres - Inside
|
Real. Used in Cdp calculation.
|
Used to determine the Cdp factor.
|
|
Off Design Pres - Outside
|
Real. Used in Cdp calculation.
|
Used to determine the Cdp factor.
|
|
Inside Pressure - Min
|
Real. Used in Ccf calculation.
|
The minimum inside pressure, which is used to determine the Ccf factor.
|
|
Inside Pressure - Max
|
Real. Used in Ccf calculation.
|
The maximum inside pressure, which is used to determine the Ccf factor.
|
|
Outside Pressure - Min
|
Real. Used in Ccf calculation.
|
The minimum outside pressure, which is used to determine the Ccf factor.
|
|
Outside Pressure - Max
|
Real. Used in Ccf calculation.
|
The maximum outside pressure, which is used to determine the Ccf factor.
|
|
Tensile Strength
|
Real (10^3 psi). Used in Ccf calculation.
|
The tensile strength of the filter media.
|
|
Cold Start Temperature
|
Real (Degrees C). Used in Ccs calculation.
|
Used to determine the ratio of cold start fluid viscosity in relation to the normal operating fluid viscosity
|
|
% Water Volume
|
Real. Used in Ce calculation.
|
The percentage of water in system fluid. Considers the effect of incompatible fluids and materials.
|
|
System Fluid Type
|
Choice List. Used in Ccs and Ce calculations.
|
The type of fluid in the filter, which is used in determining viscosity factors. Choices are:
• Kerosene
• Other
|
|
Temperature Rise
|
Real (Degrees C). Used in Ct and Ccs calculations.
|
The temperature rise from the ambient subassembly temperature to this component. The temperature rise plus the ambient temperature is equal to the operating temperature of the device.
