The internal pressure of a cylindrical tank is given as 1150 KPa. If the allowable strength at the longitudinal joint is 500 KN/m while the allowable strength at the girth joint is 240 KN/m, determine the maximum diameter of the cylinder tank.

Water backs up behind a concrete dam as shown in figure Leakage under the foundation gives a pressure distribution under the darri as indicate If the water depth, h, is too great, the dam will sopple over about its toe (Point A) For the dimensions given, determine the factor of safety agarest overtuming moment if L-120 fh and h - 50 n. Base your analysis on a unit length of the dam The specific weight of the concrete is 150 ib/tt3 Water

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.
