A long 35-cm-diameter cylindrical shaft made of stainless steel 304 (k = 14. 9 W/m2·K, rho = 7900 kg/m3 , cp = 477 J/kg·K, and α = 3. 95 × 10-6 m2 /s) comes out of an oven at a uniform temperature of 500°C. The shaft is then allowed to cool slowly in a chamber at 150°C with an average convection heat transfer coefficient of h = 60 W/m2 ·K. Determine the temperature at the center of the shaft 20 min after the start of the cooling process. Also, determine the heat transfer per unit length of the shaft during this time period

Answers

Answer 1
To determine the temperature at the center of the shaft 20 minutes after the start of the cooling process, we can use the 1-D steady-state heat conduction equation:

q'' = -k*(dT/dx)

where q'' is the heat flux per unit area, k is the thermal conductivity of the shaft, T is the temperature, and x is the distance from the surface of the shaft.

The boundary conditions for this problem are:
T(r=R, t) = 150°C (convective heat transfer coefficient)
T(r=0, t) = 500°C (initial temperature)

We can use the above equation to get the temperature distribution in the shaft, and then integrate it to find the temperature at the center of the shaft.

To determine the heat transfer per unit length of the shaft during this time period, we can use the following equation:
q' = hA(T_surface - T_ambient)

where q' is the heat transfer per unit length, h is the convective heat transfer coefficient, A is the surface area, T_surface is the temperature of the surface and T_ambient is the temperature of the surrounding environment.

Please note that the above information is just an overview of how to solve the problem and is not a complete solution. The above equations and boundary conditions may require some modification according to the given problem, and the exact solution would require a detailed mathematical analysis.

Gross errors, often known as "outliers," are errors that are not systematic or random. They are inherently unpredictable and frequently huge.

Gross errors result from experimenter negligence or device malfunction. These “outliers” are typically ignored when analyzing data because they are far above or below the genuine value.

Answers

To calculate the heat transferred to the reactor per mole of entering 1-butene, we need to determine the enthalpy change for the reaction and then multiply it by the conversion of 1-butene to 1,3-butadiene.
The balanced equation for the reaction is
C4H8(g) + 3H2(g) → C4H6(g) + 3H2(g)

The enthalpy change for the reaction can be calculated using the standard enthalpies of formation for 1-butene and 1,3-butadiene.
The heat transferred to the reactor per mole of entering 1-butene can be calculated by multiplying the enthalpy change for the reaction with the conversion of 1-butene to 1,3-butadiene (33%).

As the enthalpy change of the reaction is not provided, it is not possible to calculate the heat transferred to the reactor per mole of entering 1-butene.

What rock may be formed by fractional crystallization of olivine and pyroxene?

Answers

Ultramafic rocks may be formed by fractional crystallization of olivine and pyroxene. Mafic: Rocks, such as basalt, that are mostly composed of pyroxenes and olivine as well as plagioclase feldspar and/or feldspathoid minerals.

Ultramafic rocks are igneous and meta-igneous rocks having a very low silica content (less than 45%), typically >18% MgO, high FeO, low potassium, and are typically made of more than 90% mafic minerals, though the words are not entirely identical (dark colored, high magnesium and iron content). Ultramafic rocks make up the mantle of the Earth. A broader definition of ultrabasic includes volcanic rocks with low silica concentration that aren't necessarily highly enriched in Fe and Mg, like carbonatites and ultrapotassic igneous rocks. Large, layered ultramafic intrusions that frequently contain distinct rock types in strata are common locations for ultramafic rocks. The chemistry of the magma from which they crystallized is not represented by these sorts of cumulate rocks. The pyroxenites, peridotites, and dunites are ultramafic intrusives. Troctolite, which contains more calcic plagioclase, is one of the rarer forms. These are classified as anorthosites. The higher parts of the layered ultramafic sequences frequently contain gabbro and norite. There are additional occurrences of phlogopite and hornblendite.

which type of rock is most likely to contain fossils? igneous, sedimentary, or metamorphic?

Answers

The correct response is b. sedimentary. Igneous rock, metamorphic rock, and sedimentary rock are the three basic categories of rock. Sedimentary rock preserves almost all fossils.

Sedimentary rocks are a class of rock created by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. The mechanisms that lead to these particles settling in one location are collectively known as sedimentation. Sediment is the collective name for the tiny pieces that make up sedimentary rocks. It can be made up of biological or geological waste, such as minerals (organic matter). The formation of the geological debris resulted from the weathering and erosion of pre-existing rocks or from the solidification of molten lava blobs that volcanoes had released. Water, wind, ice, or mass movement, together known as agents of denudation, convey the geological debris to the site of deposition. The bodies and pieces of dead aquatic species suspended in water and slowly accumulating on the bottom of water bodies, primarily their shells and feces, are known as biological detritus (marine snow). Sedimentation can also happen when dissolved minerals precipitate out of water.

Is the charge the current?

The rate at which positive charge flows is called current. The movement of electrons, ions, as well as other particles can produce current. Since electrons have a negative charge, they move in the reverse direction from current.

So the only hope is to hop on the rocks on the river, which are positioned in a straight line. The positions of the rocks are measured from the start location, assuming that the bunny starts at the 0 cm mark. The opposite bank could be treated as a big rock. It is the final rock in the tuple of rocks.In the Figure below, the rocks are at locations 32, 46, 70, 85, 96, 123, and the opposite riverbank is at location 145.The bunny will jump as far as it could for each hop. What is the smallest number of jumps it needs to take to reach the other side of the river? For the above example, it needs to make 3 jumps, as shown in the diagram above.You may assume that there are at most 20 rocks (including the opposite bank).Write a function rabbit that takes in a tuple representing the locations of the rocks. Your function should return the minimum number of jumps needed, or -1 if it is not possible for the bunny to reach the other side of the river.
