1.A reservoir at elevation 700 ft will supply a second reservoir at elevation 460 ft. The reservoirs are connected by 1300 ft of 24-in cast-iron pipe and 2000 ft of 20-in cast iron pipe in series. What will be the discharge delivered from the upper reservoir to the lower one?
2.A stainless steel tube with an outside diameter of 59 mm and a wall thickness of 5 mm is used as a compression member. If the axial normal stress in the member must be limited to 220 MPa, determine the maximum load P that the member can support.
