7. Consider an element that conducts heat as shown below with length L, cross sectional area A, and heat conductance k. Nodes 1 and 2 have temperatures of T, and T2. The heat flux q due to conduction is given by: dT ΔΤ q = - k dx Ax This relationship is analogous to Hooke's Law from the prior problem. Heat transfer by conduction Qc is given by: Oc = qA Use equilibrium requirements to solve for the heat transfer by conduction Qci and Qcz at the nodes and use these equations to derive a "conductance matrix" (or the stiffness matrix due to conduction which is the analog of the stiffness matrix) for this heat conducting element. For the sign convention, consider heat flux positive when heat flows into the element and negative when it flows out of the element. Show your full matrix equation and the conductance matrix.

The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation?

Let's assume that the outdoor temperature in your region was 1 C on 26.12.2002. Let's assume that you use a 2088 W heater in the room in order to keep the indoor temperature of the room at 20 ° C. In the meantime, a 68 W light bulb for lighting, a computer you use to solve this question and load it into the system (let's assume it consumes 217 W of energy), you and your two friends (three people in total) are in the room to assist you in solving the questions. A person radiates 45 J of heat per second to his environment. When you consider all these conditions, calculate the exergy destruction caused by the heat loss from the exterior wall of your room.

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…
