##### Reference no: EM131154126

Heat conduction in a nuclear fuel rod assembly (Fig. 10B.3) considers a long cylindrical nuclear fuel rod, surrounded by an annular layer of aluminum cladding. Within the fuel rod heat is produced by fission; this heat source depends on position approximately as

Here Sn0 and b are known constants, and r is the radial coordinate measured from the axis of the cylindrical fuel rod. Calculate the maximum temperature in the fuel rod if the outer surface of the cladding is in contact with a liquid coolant at temperature TL. The heat transfer coefficient at the cladding-coolant interface is hL, and the thermal conductivities of the fuel rod and cladding are ks andkC.

#### Determine the air-gap flux density

If the bore of the machine is 42 cm in diameter, its axial length is 28 cm, and each pole subtends an angle of 60°, determine the air-gap flux density. (Note that the number

#### Concentration of a poorly soluble salt

1. Formation of kidney stones occurs when concentration of a poorly soluble salt (for example, calcium oxalate) in urine exceeds its solubility limit. Assume that a kidney sto

#### Calculate the percentage conversion of hexane

The stack gas emerges at 760 mm Hg. Calculate the percentage conversion of hexane, the percentage excess air fed to the burner, and the dew point temperature of the stack gas.

#### How much heat is removed during the cooling step

A sealed tank contains saturated steam at 5 bar. The volume of the tank is1m3. Heat is added until the pressure in the tank pressure doubles. What is the final temperature?

#### What will be the power consumption

The diameter of the impeller is 3 m and the impeller is installed 1,35 m abobe the bottom of the 2o ft tank. If the temperature is 30 C and the impeller is rotated at 30 r/m

#### Determine the temperature and composition of the two phases

A stream that contains a methanol/ethanol mixture with 32% mol methanol is flashed to 100 °C to a pressure such that the molar rate of the vapor stream is 75% of the feed. D
