Find f(x) linear function?

Is this a linear function? In that case, f(6) should be simply 13+5 = 18 , but it is not. According to the requirement of a linear function , f(a) +f(b) = f(a+b). According to this requirement, 4x-3 is not a linear function, but an affine function. However, it is equation of a straight line. …

Superheated water vapour at 180 psia and 500 degrees Farenheit is allowed to cool at a constant volume until..?

fi(P,T) = f(180,500 SUPERHEATED Pressure 180,0000 psia Temperature 500,0000 F Sat. temperature 373,0757 F Enthalpy 1271,1855 Btu/lbm Internal energy 1169,8170 Btu/lbm Entropy 1,6376 Btu/lbm/F Specific volume 3,0433 ft3/lbm Density 0,3286 lbm/ft3 Specific heat (Cp) 0,5441 Btu/lbm/F Final state will have density the same as intial density(constant volume) or same specific volume.
