Oil sg = 0.84 flowing through a pipe has %3D a total heal loss 3ft from pt.1 to pt.2. As the figure is shown, find the pressure (in pound/ squarefeet) at pt.2. Point 1 D, = 6 in P, = 65 psi Q - 2.08 cfs 10.70 fe Q = 2.08 cfs Point 2 D, - 9 in P2 =? 4.00 ft

Oil (kinematic viscosity = .0003 ft^2/s and specific weight = 53.7 lb/ft^3) flows from A (zA = 225.5 ft ) to B (zB = 235.84 ft) at a rate of 290 gpm. The pipe material is commerical steel and the pipe length from A to B is 7320 ft. The required minimum pressures at A and B are PA = 55 psi and PB = 13 psi. Determine the minimum pipe size to satisfy the pressure requirements through iteration with the Moddy Diagram. Round up the diameter to the nearest 1 inch.

A hollow steel [E = 30,000 ksi] tube (1) with an outside diameter of 3.500 in. and a wall thickness of 0.500 in. is fastened to a solid aluminum [E = 10,000 ksi] rod (2) that has a 2.000-in.-diameter and a solid 1.375-in.-diameter aluminum rod (3). The bar is loaded as shown. Assume L1= 55 in., L2= 40 in., L3 = 25 in., R = 31 kips, Q = 11 kips, and P = 27 kips. Determine (a) the change in length of steel tube (1).
