Two very long slender rods of the same diameter are given. One rod is of aluminum and has a thermal conductivity k1=200W/ (m.0C), but the thermal conductivity k2 of the other rod is not known. To determine the thermal conductivity of the other rod, one end of each rod is thermally attached to a metal surface which is maintained at a constant temperature T0. Both rods are losing heat by convection with a heat transfer coefficient h into the ambient air at T∞. The surface temperature of each rod is measured at various distances from the hot base surface. The temperature of the aluminum rod at x1=40cm from the base is the same as that of the rod of unknown thermal conductivity at x2=20cm from the base. Determine the thermal conductivity of k2 of second rod.

Expert Solution

this question is from chapter "FINS"

we need to study the temperature profile of fins or can be taken from databook also.

A steel rod 0.450 m long and an aluminum rod 0.250 m long, both with the same diameter, are placed end to end between rigid supports with no initial stress in the rods. The temperature of the rods is now raised by 60.0 ∘C. What is the stress in each rod? (Hint: The length of the combined rod remains the same, but the lengths of the individual rods do not.) Psteel,Paluminium = ?

A 50 cm long rod is half aluminum and half copper. The aluminum end is in boiling water. The end of an aluminum rod (50 cm long) is maintained at 100 C by immersing in a pot of boiling water and the other end at 00C by an ice-water mixture. If the cross-sectional area of the rod is 1.3 cm2, how much will the rod melt in 20 min? What will be the steady temperature at the Al-Cu junction?

A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. (Figure 1) Part A What is the fundamental frequency of a 2.20 -long aluminum rod? The speed of...

An aluminum rod with a square cross section is 1.2 m long and 5.0 mm on edge. (a) What is the resistance between its ends? (b) What must be the diameter of a cylindrical copper rod of length 1.2 m if its resistance is to be the same as that of the aluminum rod? The resistivity of aluminum is 2.75 × 10-8 Ω·m and the resistivity of copper is 1.69 × 10-8 Ω·m.

The diameter of steel rods manufactured on two different extrusion machines is being investigated. Two random samples of sizes ?1 = 20 and ?2 = 24 are selected, and the sample means and sample variances are ?̅̅1̅ = 9.22, ?1 = 0.55, ?̅̅2̅ = 9.43, and ?2 = 0.62, respectively. Assume that ?1 2 ≠ ?2 2 and that the data are drawn from a normal distribution. Is there evidence to support the claim that machine 1 produces rods with...
