A syngas fuel consists of these following volumetric composition: 75% methane and 25% butane. The syngas at 100 kg/hour and 25 C is mixed with 20% excess air at 30 C. Due to incomplete combustion mechanics, 10%v of the syngas carbon is partially oxidized and forms carbon monoxide.

If the products of combustion are at 600K, obtain the combustion heat transfer rate from the system.

A steam powerplant operating on an ideal Rankine Cycle is operating at a boiler pressure of 5.75MPa, steam enters the turbine at 500°C and expands to 147kPa. If the powerplant is producing 5MW of energy find the following:

1. Enthalpies at each point of the cycle 1,2,3,B (hint: you will have to interpolate horizontally for point 1 and interpolate for the f,g,fg values for point 2)
2. Net work in kj/kg
3. Mass flow rate of throttle steam used by the powerplant
4. Heat added in the boiler
5. Heat rejected in the condenser
6. Cycle Thermal efficiency

Q1.
a. List and discuss the three basic types of engineering production.
b. List the role of Quality Control and Inspection during the manufacture of a product.
c. List any two reasons why automation is preferred for a modern manufacturing concern.
d. List any two factors that compel industrial outlets to computers in design, manufacturing and
allied services.

A round composite bar is used to conduct heat. It is held at 600K at one end and 1000K at the other end but all other surfaces are insulated. The two end pieces of the bar are Stainless Steel (AISI304), and the middle piece is Copper. The length of each piece of the bar is 0.2m (total length is 0.6m) and the diameter is 0.07m.

A) Change the middle piece of the round bar to stainless steel to make the bar of uniform material. Change the boundary conditions to make this bar a fin with a constant base temperature and with an insulated end. Apply convection at all cylindrical surfaces except the base and the tip. The convection coefficient, h = 50 W/(m²·K), and fluid temperature of T_∞ = 300K. Plot the temperature

B) Plot the analytical solution of the temperature distribution for this fin versus the fin length (T vs x). Include your hand calculations.

The system has zero -3, poles -2 ± j and gain 5.

4. Use music wire to make a series of springs with wire diameters [0.075”, 0.080”, 0.085”, 0.090”].
Each spring should have a free length of 3” and rate of 50 lbf/ft and exactly 20 total coils. The
ends are squared and ground and the load factor of safety should be 1.1.
For each wire size, list the figure of merit and the spring index, C.
All else being equal, which wire diameter makes the most meritorious design?

Design a double-dwell cam to move a follower from 0 to 2.5 in. in 60°, dwell for 120°, fall 2.5 in. in 30°, and dwell for the remainder. The total cycle must take 4 sec. Size the cam for a 1-in. radius roller follower considering pressure angle and radius of curvature. Use eccentricity only if necessary to balance these functions. Plot both these functions. Draw the cam profile. Repeat this for a flat-faced follower. Which one would you use?

heat transfer

The double-glazed window with a height of 1.2m and a width of 2m has a gap of stagnant air (k = 0.026W / m ° C) with a width of 12mm between the glass of 3mm (k = 0.78W / m ° C). On a day when the outside temperature is kept at 24 ° C, find the continuous heat transfer rate and inner surface temperature in this glass window. (Take the heat transfer coefficients h1 = 10W / m² ° C and h2 = 25W / m² ° C on the inner and outer surface of the window and neglect the number of heat transfer coats by radiation)
b) Interpret how the heat transfer would have been if there was a vacuum between the two glasses (air was completely discharged).
