Doctor Consultation
Most of our patients gained relief through our treatment and many gained confidence from our motivating consulting approach.
"Actual (given efficiency η=0.85)" η = 0.85 η = (h1 - h2a)/(h1 - h2s) h2a = h1 - η*(h1 - h2s) W_a = h1 - h2a EES replaces table lookup:
EES is case-insensitive but uses ^ for power. 3. Implementing Iso-Processes in EES a) Isobaric (( P = constant )) Cengel rule: ( P_1 = P_2 ), ( Q - W_b = \Delta H ) (for closed system, often ( W_b = P\Delta V )).
P1 = 200 [kPa] P2 = P1 T1 = 25 [C] m = 1 [kg] Fluid$ = 'R134a' v1 = volume(Fluid$, P=P1, T=T1) u1 = intEnergy(Fluid$, P=P1, T=T1) h1 = enthalpy(Fluid$, P=P1, T=T1)
R = 0.287 [kJ/kg-K] "Air" T = 300 [K] m = 1 [kg] P1 = 100 [kPa] P2 = 500 [kPa] v1 = R T/P1 v2 = R T/P2
"Given final state: superheat to T2" T2 = 80 [C] v2 = volume(Fluid$, P=P2, T=T2) u2 = intEnergy(Fluid$, P=P2, T=T2) h2 = enthalpy(Fluid$, P=P2, T=T2)
"Isentropic turbine work" W_s = h1 - h2s "kJ/kg"
