b) A tank shown in Figure-2 below is used to mix methanol and salt. The tankinitially contains 1 m³ of methanol. Salt is provided into the tank witha volumetric flow rate of Fsalt= 0.2 m³ s¹. A stream with perfectly mixedmethanol and salt leaves the tank with a volumetric flow rate ofF = 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/sPsalt=2160 kg/m³V(t)F=0.1 m³/sFigure-2: A mixing tank of methanol and salt.d(V (t)Psalt)dtSalt+methanolThe mass balance of salt in the tank is given by,d(V (t) (Psalt +Pmethanol))dt= Fsalt Psalt - FPsaltwhere Psalt is the density of salt and equal to 2160 kgm ³. The total massin the tank is given by,= Fsalt Psalt - FPsalt - FPmethanolwhere Pmethanol is the density of methanol and equal to 800 kgm-³. Whenthe 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 balanceequations.(Hint: First, discretise the total mass equation to find time when the volumeof mixture is equal to V = 0.5m³).

Following the theorem of corresponding states, for compressibility factor Z> 1.0 (hard fluid) The fluid has mass, but its molecule have (or assumed to have) zero volume The molecules do not exert any force on the neighboring molecules (i.e., no attractive or repulsive forces). Repulsive forces are dominant between molecules and the neighboring molecules Attractive forces are do molecules bet ules and the neighboring
