What type of pumps are used in hydraulic combinaton systems?
two-phase (two-step) or round pumps

How material properties, such as glass transition temp, conductivity, and crystallinity, change with elevating temperatures! Meanwhile, corrosion is another pressing issue in our daily life. What are the origin and underlying mechanisms? Why Metals oxidize so fast!? How do you extrude polymer into thin fibers for clothes, fences, and fibers? and how do your favorite sports connect with composite materials?

Air at 60oC and 1 atm enters a smooth tube having a diameter of 2 cm and length of 10 cm. The air velocity is 40 m/s: 1- What constant heat flux must be applied at the tube surface to result in an air temperature rise of 5oC? 2- What average wall temperature would be necessary for this case?

Answer: (1) qs = 11841W/m2    (2) Tw = 97oC

Liquid bismuth flows at a rate of 4.5 kg/s through a 5.0-cm-diameter stainless-steel tube. The bismuth enters at 415oC and is heated to 440oC as it passes through the tube. If a constant heat flux is maintained along the tube and the tube wall is at a temperature 20oC higher than the bismuth bulk temperature, calculate the length of tube required to effect the heat transfer. For liquid bismuth: ? = 1.34 ?10-3 kg/m· s Cp = 0.149 kJ/kg.oC k = 15.6 W/m. oC Pr = 0.013

Answer: L = 1.57 m

2. What are the Limits of the equipment being used in the Fused Deposition Modeling (FDM), apart from producing small parts only?

Explain why in welded components, residual compressive stresses are as detrimental as residual tensile stresses, but in unwelded components residual compressive stresses are beneficial.

A new type of bird capable of self-propulsion is designed in order to maximise its flying distance in the presence of aerodynamic drag. This new bird, having the initial mass of mo, generates thrust by ejecting 1% of its initial mass (0.01mo) with the velocity of 50m/s in the direction opposite to the bird’s instantaneous velocity relative to the bird every 0.1s (similar to how rockets generate thrust).

function [vx_f,vy_f,m_f] = mass_ejection(vx_i,vy_i,v_eb,m_i,m_e)

% Inputs:

% vx_i: Velocity component in x direction before ejection

% vy_i: Velocity component in y direction before ejection

% v_eb: Ejection velocity of the mass relative to the bird

% m_i : Mass of the bird before ejection

% m_e : Ejection mass

% Outputs: % vx_f: Velocity component in x direction after ejection

% vy_f: Velocity component in y direction after ejection

% m_f : Mass of the bird after ejection

(d) Using the function written incorporate the mass ejection mechanism into the existing model with drag (remember that you need to run this function every 0.1s and use the output to update the velocity and mass of the bird). Compute and plot the trajectory of the new bird and compare it with the trajectory of the original bird with the same initial conditions. On your plot, indicate with symbols where mass ejections happen. The bird is launched with the initial velocity of 10m/s at the angle of 50? from the horizontal. The initial mass of the bird, mo is 1kg. The release point of the bird is 2m directly above the base of slingshot and the base of slingshot can be considered as the origin (figure 5). The density of air is 1.2 kg/m3 and use CD = 1. The bird can be treated as a sphere with a radius of 0.15 m. on matlab

4. In plastic injection molding, temperature, time in mold, and injection pressure each play an important role in determining the strength of the part. At MAR Inc., experimenters are studying the effects on part strength when the temperature is set at either 250o, 275o, or 300oF; the time in mold is either 5, 7, or 9 seconds; and the injection pressure is either 200, 250, or 300 psi. Create a table show the factors and their levels for this information.

5. For the information in problem 4, how many tests would be necessary to test every possible treatment (a full factorial experiment)?.

6. A team is currently working to redesign a compressor assembly cell. The team has several design changes that they want to test using design of experiments. They want to decrease the cell’s assembly and packing throughput time. Currently, it takes 45 minutes to assemble and pack a compressor. The team is considering three changes: Reduce current 36 inch conveyor width to either 18 inch or 24 inch; Install new parts presentation shelving, either flat surfaced or angled Line form: either straight or curved Implement the first four steps of the experiment design process in slide 15. Comment on how to interpret and verify the results
