Explanation Data: F u − downward on CD F L − upward on DE b − hight of the cylinder Δ A = 1 2 θ R 2 The vertical force on the submerged semicircular CDE can be divided into two forces The resultant force of these two forces give the buoyancy force on this semicircular According to the Archemidie's Law (The Buoyant force that is exerted on a body immersed in fluid, is equal to the weight of the fluid that the body displaces) Calculation: Force = Pressure(b ρ g) × Area Δ F = P Δ A

The feed flow rate to an adiabatic continuous stirred tank reactor (CSTR) in which an exothermicreaction is occurring is increased from 1000 to 1400. kg/h, causing the outlet temperature to change as shown:a) Briefly explain on a physical basis why the temperature in this system oscillates after a step increasein the inlet flow rate. Be clear, complete, and concise. c) You know that this oscillating response cannot be that of two first order processes with real timeconstant acting in series. Assuming the reaction is first order and the CSTR operates with constant holdup,derive the block diagram with all transfer functions indicating how the temperature would respond to the feedflow rate step change (W’(s) as input and T’(s) as output). An intermediate variable in this block diagram willbe the concentration of A in the reactor, represented by CA’(s). d) A correct result for part c) will include a feedback loop in the block diagram, indicating the responsein T to a change in w is not…

Spur gears Note : Exam is open notes &tables / Answer all questions. Q.1. The press shown for Figure.1 has a rated load of 22 kN. The twin screws have double start Acme threads, a diameter of 50 mm, and a pitch of 6 mm. Coefficients of friction are 0.05 for the threads and 0.08 for the collar bearings. Collar diameters are 90 mm. The gears have an efficiency of 95 percent and a speed ratio of 60:1. A slip clutch, on the motor shaft, prevents overloading. The full-load motor speed is 1720 rev/min. (a) When the motor is turned on, how fast will the press head move? (Vm= , Vser. = ) (5M) (b) What should be the horsepower rating of the motor? (TR=, Tc= Pser. = " Bronze bushings Foot Motor Bearings watt, Pm= watt, Pm= h.p.) (20M) 2['s Fig.1 Worm Collar bearing

Problem 2 (55 pts). We now consider the FEM solution of Problem 1.(a) [5pts] Briefly describe the 4 steps necessary to obtain the approximate solution of thatBVP using the Galerkin FEM. Use the minimum amount of math necessary to supportyour explanations.(b) [20pts] Derive the weak form of the BVP.(c) [10pts] Assuming a mesh of two equal elements and linear shape functions, sketch byhand how you expect the FEM solution to look like. Also sketch the analytical solutionfor comparison. In your sketch, identify the nodal degrees of freedom that the FEMsolution seeks to find.(d) [10pts] By analogy with the elastic rod problem and heat conduction problem considered in class, write down the stiffness matrix and force vector for each of the twoelements considered in (c).(e) [10pts] Assemble the global system of equations, and verbally explain how to solve it.
