Chapter 5, Problem 5.33P

A 100 ft length of buried, uninsulated steel pipe carries chilled water at a mean temperature of 42 F. The pipe is 30 in. deep and has a 4 in. diameter. The thermal conductivity of the earth is about 8 Btu-in .(hr-ft 2 -F) . Assume the temperature of the ground near the surface is 70 F and estimate the heat transfer rate from the water.

Q Derive (continuity equation)? I want to derive clear mathematics.
motor supplies 200 kW at 6 Hz to flange A of the shaft shown in Figure. Gear B transfers 125 W of power to operating machinery in the factory, and the remaining power in the shaft is mansferred by gear D. Shafts (1) and (2) are solid aluminum (G = 28 GPa) shafts that have the same diameter and an allowable shear stress of t= 40 MPa. Shaft (3) is a solid steel (G = 80 GPa) shaft with an allowable shear stress of t = 55 MPa. Determine: a) the minimum permissible diameter for aluminum shafts (1) and (2) b) the minimum permissible diameter for steel shaft (3). c) the rotation angle of gear D with respect to flange A if the shafts have the minimum permissible diameters as determined in (a) and (b).
