A two-jet Pelton wheel produces power of 2 MW at 400 rpm. The diameter of the wheel is 1.5 m. The gross head (i.e., measured from the water surface in the reservoir to the nozzle) is 200 m. Consider the head loss in the penstock and nozzle is 10% and the deflected velocity by the bucket is reduced by 10% due to friction. Given that the deflected angle is 165° and the nozzle efficiency is 0.95, determine a) Nozzle head, b) Euler head, c) Velocity ratio, d) Diameter of the jet, e) Wheel power, and f) Mechanical efficiency.

Introduction The purpose of this laboratory is for the student to design (synthesize) a clocked synchronous finite state machine, and verify its operation in simulation. The student will invent their own state machine, and follow the design flow (process) to successfully create it. Design Requirements The clocked synchronous state machine must meet the following requirements: 4 States Only 1 Input Only 1 Output Only, or Output Coded State Assignment D-Type Flip-Flops All Circuits Minimized Design Using the techniques discussed in this cour date, design your circuit according to the design flow outlined below: Write a Word Description of your state machine One or two paragraphs maximum A colleague should be able to create the State Diagram from your Written Description only Create a State Diagram that represents the state machine in the word description Your state diagram, and word description MUST match Develop a State Table from the state diagram Develop a Transition Table from the state table, and Include the Output Z Develop K-Maps for each next state variable Q1, Q0°, and also for the Output Z Develop Minimized Circuits for Q11°, Q0°, and also for the Output Develop the Final Clocked Synchronous State Machine Simulation Verify your design in simulation Conclusion Given the process described above, what defines the successful completion of this laboratory? Did you achieve this? What challenges did you encounter?

Problem 4) The figure below shows a picture of a "horsehead" oil pump (although this horsehead is painted to look like a bird). If you've ever been to Texas you've seen one of these. Head moves up and down Beam is pivoted here The well runs at 8 cycles/min., 60 min./hr. and runs 24 hrs/day, 365 days per year. It is expected to last for 5 years before the well runs dry. Breakdowns mean lots of lost money therefore a reliability of 99.0% is needed for this component. The load that the connecting rod sees is much higher when it is pulling the oil and the well rod up than when it is pushing down. Assume that the actual loading is roughly sinusoidal and that the force magnitudes are: Max force on down-stroke = 1,000 lbf DOWN (still down, not up.) Max force on up-stroke = 20,000 lbf DOWN Oil down here QUESTIONS: a) On the drawing above, indicate the point(s) where fatigue failure is most likely to occur. Explain WHY you chose this point. b) Draw a graph of load vs. time for the connecting rod c) In words and equations (not numbers, just equations) explain the approach that you will use to find the factor of safety against fatigue failure of the rod. d) Find the factor of safety against fatigue failure of the connecting rod. The oil company discovers that they can get more oil out of the well if they add a motorized impeller at the very end of the well rod in order to stir-up the oil. The impe looks like this: I The pump consists of a motor that turns a crank, which is attached to one end of the main beam. The beam is pivoted near its center so that the motion of the crank causes the beam to "see-saw" up and down. This causes the head of the pump to move up and down in nearly a straight line. Connected to the head (at the end of the bird's beak) is a connecting rod. This rod connects the head to the well rod (which you can't see because it's under the ground). When the head travels down it pushes down on the connecting rod, which then pushes the well rod down into the well. When the head moves back up it pulls on the connecting rod, which pulls up the well rod, which sucks oil up with it. You are to perform a fatigue analysis on the connecting rod. Here is information that you may need: 1) The load on the connecting rod from the pump head to the well rod is straight through the longitudinal axis of the rod. 2) The rod is machined from AISI 1040 quenched and tempered at 400 deg. F. 3) The rod is a solid round bar. 4) Dimensions of the rod are shown in the diagram on the next page. The impeller is attached to the end of the well rod and turned using a hydraulic motor attached to the end of the well rod as shown in the sketch below: WELL ROD MOVES UP AND DOWN WITH PUMP HORSEHEAD PUMP IS UP THERE 5) The length of the rod is 5 feet. 6) The oil that is being pumped has a viscosity of 100 micro-poise. 7) The operating temperature of the rod is 150°F (it's Texas in the summer). 8) Both ends of the rod are threaded so that the rod can be connected to the head and WELL ROD to the well rod. Just below the point where it is threaded the rod is turned-down to a diameter of 4.75 in. The transition between these two diameters has a 0.125 in. fillet (see sketch below). IMPELLER ROTATES PUTTING TORQUE ON WELL ROD R.125 BOTTOM OF THE OIL WELL MOTOR -IMPELLER $4.75 $5.00 When the impeller is turning but the well rod ISN'T moving up and down, the impeller exerts a torque of 200 ft-lbf. on the well rod in the direction opposing the rotation of the impeller. HOWEVER, when the well rod moves UP through the well the added motion of the oil over the impeller causes additional torque on the rod (this ONLY happens on the up stroke of the well). The ADDITIONAL torque varies from a minimum of 0 ft-lbf. to a maximum of 100 ft-lbf. ALL OF THE TORQUE GENERATED BY THE IMPELLER IS TRANSFERRED INTO THE CONNECTING ROD AT THE TOP OF THE WELL. In addition to this torsional force, the rod still sees the axial force which is still: Max force on down-stroke = 1,000 lbf DOWN (still down, not up.) Max force on up-stroke = 20,000 lbf DOWN You are to perform a fatigue analysis on the connecting rod. All geometry, temperature, material, operating hours, cycle frequency, reliability, and desired life specifictions are the same as in Part 1. I Estimate the safety factor for this component against failure within the required life.
