Assume that the wall shear stress, Tw, created when a fluid flows through a pipe (see Figure a) depends on the pipe diameter, D, the flowrate, Q, the fluid density, p, and the kinematic viscosity, U. Some model tests run in a laboratory using water in a 0.2-ft-diameter pipe yield the vs. Q data shown in Figure b. Perform a dimensional analysis and use model data to predict the wall shear stress in a 0.5-ft-diameter pipe through...

A C14500 hard copper pipe has an inner radius of 0.5 in. and a wall thickness of 0.125 in. If the fluid flowing through it changes the temperature of the pipe to 180°F, determine the thermal stress in the pipe. The pipe was fitted between the walls when the pipe was at 60°F. Also determine if Hooke's law is valid, if it is safe and the axial force the bar exerts on the walls. Assume the wall is rigid. 8...
