Fluid Specific Gravity
SP GRAVTY — Fluid Specific Gravity Entry (Value)
Unitless Value
Allows adjustments to be made to the specific gravity (density relative to water) of the liquid.
As stated previously in the FLUID VI section, specific gravity is utilized in the Reynolds correction algorithm. It is also utilized if
mass flow measurement units are selected for rate or total.
If a fluid was chosen from the FL TYPE list, a nominal value for specific gravity in that media will be automatically loaded. If the
actual specific gravity is known for the application fluid and that value varies from the automatically loaded value, the value
can be revised.
If OTHER was chosen as FL TYPE, a SP GRVTY may need to be entered if mass flows are to be calculated. A list of alternate fluids
and their associated specific gravities is located in the APPENDIX of this manual.
Fluid Specific Heat Capacity
SP HEAT — Fluid Specific Heat Capacity (Value)
BTU/lb
Allows adjustments to be made to the specific heat capacity of the liquid.
If a fluid was chosen from the FL TYPE list, a default specific heat will be automatically loaded. This default value is displayed as
SP HEAT in the BSC MENU. If the actual specific heat of the liquid is known or it differs from the default value, the value can be
revised. See Table 5, Table 6 and Table 7 for specific values. Enter a value that is the mean of both pipes.
