10.37 What is ffor the flow of water at 10°C through a 30-cm cast iron pipe with a mean velocity of 24 m/s?

10.60 As shown, water (15°C) is draining from a tank through a galvanized iron pipe. The pipe length is L = 2 m, the tank depth is H = 1 m, and the pipe is a 0.5-inch NPS schedule 40. Calculate the velocity in the pipe. Neglect component head loss. H Pipe of diameter D L Problems 10.59 and 10.60

10.53 Water is pumped through a vertical 10-cm new steel pipe to an elevated tank on the roof of a building. The pressure on the discharge side of the pump is 1.6 MPa. What pressure can be expected at a point in the pipe 110 m above the pump when the flow is 0.02 m³/s? Assume T = 20°C.

10.61 A pipeline is to be designed to carry crude oil (SG = 0.93, v = 10-5 m²/s) with a discharge of 0.10 m³/s and a head loss per kilometer of 50 m. What diameter of steel pipe is needed? What power output from a pump is required to maintain this flow? Available pipe diameters are 20, 22, and 24 cm.

Calculate the active earth pressure (exerted by the supported soil mass on the right) against the 10-meter-long, dense and smooth sheet pile wall shown in Figure E2:1. The ground surface is loaded with heavy construction machinery applying a pressure of q = 10.0 kPa. Other data is according to the figure.Assume the sheet pile moves sufficiently to the left to reach active failure conditions behind it, and passive failure conditions develop in the soil mass below the excavation bottom. Will the sheet pile wall hold without rain? (Calculate the forces.) Will the sheet pile wall hold if it rains? (Assume water-filled cracks.) If the sheet pile does not hold in any of the above cases – how deep would it need to be embedded in order to hold? Draw diagrams for active and passive earth pressure as well as the resultant earth pressure. gvy=grownd water level

The composite beam shown in the figure is subjected to a bending moment Mz=8 kNmMz​=8kNm.The elastic moduli for the different parts are E1=30 GPa, E2=20 GPa, and E3​=60GPa. a) Determine the reduced moment of inertia IredIred​ for the entire beam. b) Sketch the bending stress distribution in the beam.
