H2. A combustion facility is presumed to produce 9 Gigawatt-hours per year. Electricity price is 1.55 SEK per kWh. By raising the high temperature in the combustion facility från 373°C to 423°C to raise the efficiency. Calculate the repayment time for an investment of 1,730,000 SEK (operating cost staying the same). Assume that the facility is in a 12°C environment. (Clue: What expressions exist for the maximum thermal efficiency)

b) A tank shown in Figure-2 below is used to mix methanol and salt. The tank initially contains 1 m³ of methanol. Salt is provided into the tank with a volumetric flow rate of Fsalt= 0.2 m³ s¹. A stream with perfectly mixed methanol and salt leaves the tank with a volumetric flow rate of F = 0.1 m³ s1. As the flow is unsteady, the volume of mixture in the tank, V(t), is a function of time. Fsalt=0.2 m³/s Psalt=2160 kg/m³ V(t) F=0.1 m³/s Figure-2: A mixing tank of methanol and salt. d(V (t)Psalt) dt Salt+methanol The mass balance of salt in the tank is given by, d(V (t) (Psalt +Pmethanol)) dt = Fsalt Psalt - FPsalt where Psalt is the density of salt and equal to 2160 kgm ³. The total mass in the tank is given by, = Fsalt Psalt - FPsalt - FPmethanol where Pmethanol is the density of methanol and equal to 800 kgm-³. When the tank contains V = 0.5m³ of mixture, what is the mass of salt in the tank? Use the explicit Euler finite difference method to discretise the balance equations. (Hint:…
