During isobaric process m=64 kg of wet water stream at temperature t=262.7?C and pressure p=49 bar changed its specific volume from v1 =0.0018 m3/kg to v2=0.035 m3/kg. Find initial and final quality of steam, change of internal energy of steam, work done by steam, amount of heat exchanged with surroundings. Draw the process at the enthalpy-entropy diagram. From tables for p=49 bar: v’=0.0013 m3/kg, v”=0.0403 m3/kg, h’= 1148.4 KJ/kg, h”= 2794.7 KJ/kg

Question 4) If the effective pressure of the water in the pipe is 3 atm and in the case of h1 = 1m, h2 = 0.5m, h3 = 1m, h4 = 2m and h5 = 0.1m, determine the relative density of the fluid. (Accept that ρoil = 850 kg / m3, ρwater = 1000 kg / m3, ρhg = 13600 kg / m3, g = 9.81 m / s2. Neglect the pressure from the air at the height of h2.)...

Using the relationship for internal pressure πT = T (∂P/∂T)V – P, show that for a gas that obeys a truncated virial equation of state: Z = PVm/RT = 1 + B(T)/Vm, the internal pressure may be approximated as πT ≈ RT2(Vm)-2∙(ΔB/ΔT). Estimate the internal pressure at 1.0 bar and also at 10.0 bar for a hypothetical real gas at 275K given that B(T) = -28.0 cm3⋅mol-1 at 250K and -15.6 cm3⋅mol-1 at 300K for this gas.
