EEE 304 LAB SHEET ACTUAL EXAM PAPER
2026 QUESTIONS WITH ANSWERS
GRADED A+
◍ Emmanuel Collins.
Answer: department chair for mechanical engineering
◍ As mentioned in the video lecture, the heat transfer problem to find the
unknown thermal conductivities of the rods in our experiment can be
approximated as ___________. Select all that apply.(LAB 3)Perfect
insulation of the rodsConstant properties of the material such as thermal
conductivities1-Dimensional heat conduction along the axis of the rods (or
radial direction for a solid disc experiment)Transient heat conduction.
Answer: ALL BUT TRANSIENT HEAT CONDUCTION
◍ Resistance Temperature Detectors (RTD) measure the temperature by(LAB
1).
Answer: The change in electrical resistance in pure metals as a function of
temperature
◍ The thermal contact resistance should be expected to increase when the rods
are pressed against each other (lab 3).
Answer: FALSE (gap is closing --> increasing pressure means decreasing
resistance)
◍ Heat Transfer through a rod (lab 2).
Answer: Q = -kA(dt/dx)
◍ Under natural convection, the performance of plate-fin heat sinks is not
affected by the heat sink orientation such as horizontal vs vertical. (LAB
10).
Answer: False
, ◍ Biot number equation/rule (Lab 5).
Answer: (h *(V/A_s)) / kBi MUST BE < 0.1 for Lumped Capacitance
◍ You will determine the time constant of a bi-metallic dial thermometer. The
temperature of the room and the coolant in the constant temperature bath to
be 25 and 100 ˚
C. What is the temperature of the bi-metallic dial thermometer at one time
constant? (LAB 1).
Answer: 72.4 ˚C
◍ CMS.

◍ When designing a fin, carbon steel is typically a better choice than
aluminum..
Answer: FALSE
◍ The plastic objects (with low thermal conductivities) may be always
considered a lumped capacitance system. (LAB 5).
Answer: FALSE
◍ alternative Bi equation.
Answer: Bi = h*Lc / k
◍ Dr. Cheryl Xu.
Answer: Mechanical Engineering
◍ Which of the following is a correct statement about the numerical analysis
above?.
Answer: Heat transfer is one-dimensional.
◍ Parallel-Flow Heat Exchanger.
Answer: Both hot and cold fluids enter the heat exchanger at the same end
and move in the same direction
◍ Cross-Flow Heat Exchanger.
