Modify the model from problem 12-16 to include the thermal capacitance of the cylinder as well as convection from the cylinder surface to the atmosphere. The heat transfer coefficient for the cylinder inside wall is h1, and for the outside wall it is h2. The thermal capacitance of the wall is CW.
Problem 12-16
Consider the system from Problem 12-5. Neglect thermal capacitance of the piston walls but include leakage past the piston to the atmosphere. Using one thermodynamic accumulator and one 4-port isentropic nozzle, construct a bond graph model of the system. The crank radius is R, crank length is L, piston area is Ap, leakage area is AL, and piston mass is m.
Problem 12-5
Consider the compression of a gas by means of a crank-piston arrangement. Let the cylinder have a single average temperature, and define thermal resistances between the gas temperature T and the cylinder temperature and between the cylinder temperature and the atmospheric temperature T0. Make a bond graph that would allow you to predict the crank torque τ for low speeds of rotation, ω. (Note that you do not have enough information to evaluate all the system parameters.)

Using the following demand schedule, compute marginal and average revenue: Quantity 1 2 3 4 5 6 7 8 Price 100 95 88 80 70 55 40 22 Suppose the marginal cost of producing the good above is constant $10 per unit.
What is the relationship between the marginal cost and the average variable and average total costs You may fill in all the appropriate numbers and draw a graph with MC, TVC, AVC, TC, ATC, TFC, and AFC
Disposable income will increase by the amount of the tax and consumption at each level of GDP will decline by the amount of the tax multiplied by the MPC.
Suppose the government doesnAc€?ct want to discourage employers from hiring research assistants and, therefore, wants to minimize the share of the tax paid by the employers. Of the three tax proposals, which is best for accomplishing this goal?
