The molar enthalpy h of a binary liquid mixture of species 1 and 2 at 300 K and 1 bar pressure is given by h = 2250x + 13050x - 3600x [J/mol] (a) (10 pts.) What are the values of the molar enthalpy of pure 1 and pure 2, h1 and h2? (b) (20 pts.) Determine an expression for H, the partial molar enthalpy of species 1. (c) (10 pts.) Obtain an expression for the enthalpy of mixing, hmix. (d) (15 pts.) If 10 mol/s of pure 1 at 300 K is continuously mixed with 5 mol/s of pure 2 at 300 K in an isothermal mixer, how much heat Q [J/s] has to be removed or supplied to ensure that the system is at constant pressure?

School of Mechatronic Engineering, Universiti Malaysia Perlis ENT346, Semester 2, 2015/2016 8. A large machine has a mass of 200 kg and is mounted on an undamped elastic foundation of stiffness, $k = 2.5 \times 10^6$ N/m as shown in Figure 6. During the operation at 110 rad/s, the machine is subject to a harmonic force of magnitude 2200 N. (i) Determine the steady-state amplitude of the machine as it operates. (ii) Determine the required stiffness of an undamped vibration absorber of mass 20 kg such that steady-state vibrations of the machine are eliminated during operation. (iii) Determine the amplitude of the absorber mass when the vibration absorber of part (ii) is used. (iv) What are the natural frequencies of the resulting two degree-of-freedom system? (v) When this absorber is used, what is the frequency range such that the machine's steady-state amplitude is less than 1.2 mm? 2200 sin(110t) 200 kg $k_{eq} = 2.5 \times 10^6$ N/m (a) Figure 6 Machine is mounted on an elastic foundation at an excitation frequency of 110 rad/s.
