- 5. A gas cylinder of volume 'V' and radius 'r' contains 1.00 mol He at a pressure PHe and 1.00 mol Ar at a pressure of PAr, and both are at a temperature T = 298.0K. At the top of the cylinder is a disc with a radius 'r' that is permeable to He but not Ar. The disc is pushed to the half volume mark. 1. How much work is required for this process to be conducted isothermally and reversibly? 2. How much does AG, AH and AS change for this process? Semi-permeable disc Ar Ar Не Не Volume = V V/2 V/21 5. G(s) = 4s2s+12. What is the work done by a system when it absorbs 47 J of heat and gain 12 J of energy? 3. How much heat is released by a system when 45 J of work is done on it to decrease its energy to 23 J? 4. Suppose a woman does 500 J of work and 9500 J of heat transfer occurs into the environment in the process. What is the decrease in her internal energy, assuming no consumption of food? 5. A thermodynamic system undergoes a process in which its internal energy decreases by 500 J. If at the same time 220 J of work is done on the system, find the thermal energy transferred to or from it.
- Wind power is defined as the use of air flow through wind turbines to provide the mechanical force to generate electricity. Wind power is an alternative to burning fossil fuels, and is renewable and produces no greenhouse gas emissions during operation. Modern horizontal-axis wind turbines often use three blades. Theoretically, the maximum power P (unit: watts) that a three-blade wind turbine can extract from the wind power can be calculated as: P = pAv³C₁. . (Equation 1) where p is the air density (kg/m³), A is the sweep area of the turbine (m²) and can be calculated from the length of the turbine blades, and v is the wind speed (m/s). Cp is the power coefficient that is unique to each turbine type. This coefficient represents the amount of kinetic energy from the wind that is captured by the turbine. From the Betz's limit law we know that the best power conversion possible is Cp,max = 0.59. Part 1 Given the following data: Blade length /= 50 m Air density p= 1.5 kg/m³ Power…Qi: (50 marks) Find the total heat flux of the composite wall when: B KA = KC = KF = 15 m. K KB = KD = 10 m.
