Question Solved1 Answer 2.11. Consider the derivation, presented in this chapter, of the energy integral equation from the governing boundary liyer energy equation. Repeat this derivation but include the viscous dissipation term in the energy equation.

3) Problem 1: (25 marks) W Turbine The following diagram illustrates a simple steam power plant. A 10kg/s flow of liquid water at T1=25°C enters the pump at a pressure of Boiler P1=100kPa and is then pumped to a pressure of 4 P2=2MPa. The boiler then heats the water at constant pressure to produce superheated vapour at T3=450°C. The steam is then expanded in the Pump 1 turbine to a final pressure of P4=100kPa. The turbine and pump are well insulated and may be Wp considered reversible. a) Find the turbine exit state (quality or temperature, whichever is appropriate). (6 marks) b) Determine the turbine power output. (4 marks) c) Evaluate the power required to operate the pump. (3 marks) d) Find the water temperature T2 at the exit of the pump. (4 marks) e) Calculate the required heat input for the boiler. (3 marks) f) If the flow velocity in the pipe at the turbine inlet is V3 = 50m/s, what is the pipe diameter? (3 marks) g) Illustrate this cycle (identifying states 1 to 4) on a T-s diagram. (2 marks)

undefined 19 If we multiply a complex number z = reis by ei', we get ei®z = re (6+0), that is, a complex number with the same r but with its angle increased by e. We can say that the vector r from the origin to the point z= x+iy has been rotated by angle e as in Figure 7.4 to become the vector R from the origin to the point Z = X +iY. Then we can write X +iY = ei®z = ei® (x + iy). Take real and imaginary parts of this equation to obtain equations (7.12).

Problem 5 6/9 points (graded) An alpha particle, consisting of two protons and two neutrons, is located at < -32,0,0 > nm and produces an electric field in all of space. A neutral Krypton atom, with polarizability a = 5.0 * 10–39 oʻm is brought to the location < 14,0,0 > nm. What is the resulting dipole moment ſ that the Krypton atom attains? (Recall the relationship between an applied electric field and the resulting dipole moment is praĒ). Please answer as a vector in Coulomb meters. 0 0 0 C*m X ✓ ✓ 0 0 0 Since the neutral Krypton atom is polarized, it produces an electric field. In fact, the electric field that it produces looks like the field of an electric dipole, whose magnitude is given by lĒnasial = 2.pl.

Kevin is receiving medical treatment for a disease wheremarijuana would help to ease his pain and suffering. In Oregon,medical marijuana is legal to purchase and use for medicinalreasons IF you have been approved by an M.D. to purchase it.Kevin's M.D. gives him a prescription for medical marijuana. Andrewthen moved to Texas. He continued to use marijuana to help to easehis pain and is arrested for violating Texas state law. Kevinargued that the highest Supreme Court of Oregon permits the use ofmedical marijuana. To-date, the federal law prohibits the use orpossession of marijuana - prescribed or not. Kevin argues that theruling of the Oregon Supreme Court would be binding precedent.a. Is Kevin correct in his argument?b. Can a state's highest court rule that it's law and rulingsare precedent over another state's law?c. If the Texas court rules against Kevin, do you think this isfair? Give your reasoning.d. Which court would have jurisdiction? Be specific. Venue isappropriate where?e. How would Kevin fair in a federal court?
