The velocity, V of stream line flow depends on the radius, r of the tube, viscosity coefficient, μ and density of the fluid. Use dimensional analysis to obtain an expression for v.

The mini-refrigerator fire was most likely caused by what type of wiring?

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
