The Prandtl number is defined as the ratio of momentum diffusivity to thermal diffusivity $\left(\text{Pr}=\frac{c_{p}\mu}{k}\right)$. The vertical surface (5.2 m high, 1.3 m wide) of a block is cooled by a moving fluid with an average velocity of $V = 3.2$ m/s. The other surfaces of the block are thermally insulated. The fluid properties are $\rho = 1.15$ kg/m$^3$, $k = 0.027$ W/m$\cdot^\circ$C, $\mu = 2.17\times10^{-5}$ kg/m$\cdot$s, and $c_p = 1160$ J/kg$\cdot^\circ$C. The surface temperature of the block is maintained at 156$^\circ$C while the temperature of the fluid is constantly 25$^\circ$C. Estimate the rates of heat loss from the plate when the fluid is moving horizontally and vertically, respectively.

For a dislocation density of 10^12cm^-2, determine the temperature at which mutual recombination gives way to annealing at fixed sink. Some necessary parameters are provided below. Ko=5*10^-4 dpa/s; change in Hm^v=0.82 eV the change in Hm^i=0.12eV; the change Sm^i=0 v=10^13 s^-1; a=0.352nm Interaction radius for interstitisls (or vacancies) with dislocation lines are both R=0.6nm. Hint: here we should assume dislocation are the only existing sinks;

Question 20 (1 point) In regards to muscle cell physiology, "excitation" marks events that link the action potentials on the sarcolemma to activation of the myofilaments occurs when stimulation ends and the the muscle fiber relaxes and returns to its resting length is the step in which the muscle fiber develops tension and may shorten results in action potentials along the sarcolemma and t-tubules

13. A sample Chromium 5, used to track red blood cells, is measured to have an initial amount of 80 milligrams. Recall that exponential decay is modeled using: $A = A_0e^{kt}$, $k < 0$ For this problem amounts are measure in milligrams and time in days. (a) (3 points) Determine $A_0$ (b) (3 points) The half life of Chromium 51 is 26.2 days, meaning half of the sample will be left at that time. Using this and part (a), find a value for $k$.

Q3. A batch of cylindrical workpieces using single pass operation is decided to produce. The cost and time components involved are as follows: cost rate (units per unit time) for all the cost = $C_x$; tool removing and replacing time per regrind is $T_x$; number of regrinds possible on a tool is N; initial cost of the tool is $C_a$ and cost of tool regrinding is $C_r$. The tool life equation is followed as $VT^n = C$ where V is the cutting speed, T is tool life, and C, n are constants. Assuming other non-productive cost, cutting cost and tool cost for the estimation of total cost. For the minimum cost per batch of the components, what will be the optimum cutting speed? Note: Show the calculation in details and use the notation given in this question. [10]
