Repeat Problem 8.12 if the pipe is on a 20° hill. Is the flow up or down the hill? Explain. Problem 8.12 The pressure drop needed to force water through a horizontal 1-in.-diameter pipe is 0.60 psi for every 12-ft length of pipe. Determine the shear stress on the pipe wall. Determine the shear stress at distances 0.3 and 0.5 in. away from the pipe wall.

Complete solution, please. Thanks!

What is the answer with full working. its a practice exam, i was just wondering how to solve it

A square steel tube having the cross section shown is used as a column of 26-ft effective length to carry a centric load of 65 kips. Knowing that the tubes available for use are made with wall thicknesses ranging from 14 in. to 34 in. in increments of 116 in., use allowable stress design to determine the lightest tube that can be used. Use σY= 36 ksi and E= 29 x 106 psi.

Please answer and show all of your nice and clear plese.
