The wall shear stress in a fully developed flow portion of a 24 -in.-diameter pipe carrying water is 2.00lb/ft2. Determine the pressure gradient, p/x, where x is in the flow direction, if the pipe is (a) horizontal, (b) vertical with flow up, or (c) vertical with flow down. (a) p/x= lb/ft3 (b) p/x= lb/ft3 (c) p/x= lb/ft3
