EC_Incomp_Fluid Functions

Create a EC_Incomp_Fluid object like this:

from engcoolprop.ec_incomp_fluid import EC_Incomp_Fluid

# Create incompressible object. (without specifying state point)
ec_inc = EC_Incomp_Fluid(symbol="Water")

EC_Incomp_Fluid Description

CoolProp has a set of incompressible fluids EC_Incomp_Fluid is a wrapper of those fluids using Engineering Units.

EngCoolProp uses units of primarily inch, lbm, lbf, sec, BTU (some use of ft and hour).:

#:c     The following are the default units for each property of Incompressible Fluids.
#:c 
#:c     T = Temperature = degR
#:c     P = Pressure = psia
#:c     D = Density = lbm/cu ft
#:c     rho = Density = lbm/cu inch
#:c     E = Internal Energy = BTU/lbm
#:c     H = Enthalpy = BTU/lbm
#:c     S = Entropy = BTU/lbm degR
#:c     Cp = Heat Capacity (const. P) = BTU/lbm degR
#:c     V = Viscosity = 1.0E5 * lbm/ft-sec
#:c     C = Thermal Conductivity = BTU/ft-hr-R

EC_Incomp_Fluid Methods

class engcoolprop.ec_incomp_fluid.EC_Incomp_Fluid(symbol='DowQ', T=None, P=None, Pmax=10000.0, show_warnings=2, auto_fix_value_errors=True)

constH_newP(P=1000.0)

Calc properties at new P with same H

constP_newH(H)

Calc properties at new H with same P

constS_newP(P=1000.0)

Calc properties at new P with same S

getStrTPD()

create a string from the TPDEHS properties

getStrTransport()

create a string from the Transport properties

get_Psat(T)

Given T in degR (Engineering units) return Psat in psia (if supported) NOTE: if not supported, return 0 for Psat

get_Tsat(P)

Calculate Tsat at given P (psia). If P is greater than max Psat, simply return Tmax.

pause_warnings()

Pause all warnings until self.show_warnings is changed

printProps()

print a multiline property summary with units

printSIProps()

print a multiline property summary with SI units

printTPD()

print a string from the TPDEHS properties

printTransport()

print a string of Transport properties

restore_warnings()

Restore the self.show_warnings flag to the last pause_warnings condition

setPD(P=1000.0, D=0.01)

Calc props from P and D NOTE: The pressure has NO EFFECT on calculated temperature for incompressible density.

setPH(P, H)

Calc properties at P and H

setPS(P, S)

Calc properties at P and H

setProps(**inpD)

Generic call using any P with supported inputs T,D,S,H:

#: for example
#: ec.setProps(T=100, P=200)
#: ec.setProps(D=0.1, P=100)
#: ec.setProps(P=100, H=20)
#:
#: Made so both:
#: setProps(T=530, P=100)  AND  
#: setProps(P=100, T=530) will work

setTP(T=530.0, P=1000.0)

Calc props from T and P

set_warnings(show_warnings=2)

Set the show_warnings flag
