Starting with the market demand and supply functions in Problem 1, determine algebraically the new equilibrium price and quantity if; the demand function changes to QD' = 12,000 - 1,000 P or to QD" = 8,000 - 1,000 P, or the market supply function changes to QS* = -4,000 + 1,000 P or to QS** = 1,000 P. Draw a figure for parts (a) and (b) and label E' and E". respectively, the equilibrium point resulting when the market demand changes to QD' or QD"; label E* and E**, respectively, the equilibrium point resulting when the market supply function changes to QS* or QS**; on the same figure, label F the equilibrium point resulting with QD' and QS*, label G the equilibrium resulting with QD" and QS**, label H the equilibrium resulting with QD" and QS**, and label J the equilibrium resulting with QD" and QS*

A US airline company will purchase 400,000 gallons of jet fuel after one month and the company wants to

do cross hedging using heating oil futures. The standard deviation of monthly changes in the spot price of

jet fuel is (in cents per gallon) 300; the standard deviation of monthly changes in the futures price for the

heating oil futures contract is (in cents per gallon) 407. The coefficient of correlation between the jet fuel

price changes and the futures price changes is 0.75. Each heating oil futures contract is for delivery of 2,000

gallons of heating oil. The current spot price of jet fuel is $1.55 per gallon and the futures price of heating oil is

$1.97 per gallon. What is the optimal number of contracts with tailing adjustment?

A high-­viscosity oil is transported through a wide rectangular duct of length L, width W and depth 2B via pressure-­driven flow. The duct is inclined at an angle b? below the horizontal plane (gravity may be assumed to act downwards in the vertical direction), and is sufficiently broad that edge effects may be neglected in the transverse (x2) direction. The pressure at the upstream end of the duct (x1=0) is Po, and at the downstream end (x1=L) is PL. The flow may be regarded as laminar and isothermal, and the oil is a Newtonian liquid;? the duct may be regarded as stationary.

(a) Starting with the appropriate form of the Continuity Equation and Equations of Motion derive an equation for determining the x1 component of velocity at steady state. Be sure to identify all assumptions and boundary conditions. You should attach a marked equation sheet showing the manner in which you simplified the Navier-­ Stokes Equations.

(b) Derive an equation for the volume flow rate of oil through the duct at steady state under these conditions.

(c) Derive an expression for the shear stress T₃₁ at the upper surface of the duct (x3 = B) at steady state.

Question From Solar Technologies....

#1)  From system engineering standpoint, describe ways as to how the hot air from a solar collector can be used in buildings.

#2) Use the data provided in example 3.15 (pp. 118-119) to compute the available power, outlet temperature, and thermal efficiency at vwind = 2 m/s (all other boundary conditions are the same as condition No. 4). Compare the results from this new condition with that from condition No. 4. Note: Please describe the procedure and equations used for the calculations, and show you work (or attach your spreadsheet).

____(giwevn question)Example 3.15 Calculation of the available power, the outlet temperatures and the thermal efficiency for a facadeintegrated air collector at 800 W/m² irradiance and an ambient temperature of 10°C. The ambient temperature equals the inlet temperature Tf,in in the collector. The air duct geometry corresponds to the examples already calculated with a collector length of 2.5 m, and the heat transfer coefficient of the rear Ub is a constant 0.65 W/m²K (side losses ignored).

a. Two concentric circles have radii of 6 mm and 12 mm. A segment tangent to the smaller circle is a chord of the larger circle. What is the length of the segment to the nearest tenth?

b. A student inscribes an angle inside a semicircle to form a triangle. The measures of the angles that are not the vertex of the inscribed angle are x and 2x-9. Find the measures of all three angles of the triangle. Explain how you got your answer.

c. Two circles in the coordinate plane with congruent radii intersect in exactly two points. Why is it not possible for these circles to be concentric?

d. A gardener wants the three rosebushes in her garden to be watered by a rotating water sprinkler. To help her, you draw a diagram of the garden using a grid in which each unit represents 1 foot. The rosebushes are at points (1, 3), (5, 11), and (11, 4). She wants to position the sprinkler at a point equidistant from each rosebush . Where would you recommend placing the sprinkler? What equation describes the boundary of the circular region that the sprinkler will cover?

Consider a cylindrical wire of radius R (indefinitely long) that carries a total steady current I such that there is a constant current density j across the profile of the wire (for the first part of this task, consider just a current density in vacuum)

a) in order to calculate the magnetic induction it is suitable to work in cylindrical coordinates. Considering Boundary conditions at ρ→∞, the magnetic induction ca be written as B=B_ρ (ρ,φ,z) e_ ρ + B_ φ(ρ,φ,z)e_ φ Use the symmetry of the infinitely long cylindrical wire(and the corresponding current density) to simplify this ansatz for the magnetic induction.

b) use maxwell´s equation (no magnetic monopoles) to show that there is no component of the magnetic induction in the radial direction. Hint: use Gauss theorem together with a cylindrical volume.

c) How does the result of your calculation change if only the conductor of the wire has a magnetic susceptiblity χ>0? Hint: use the material equations and the equation for linear media.
