1.What are the interface design boundaries and issues for the design and installation of a new toilet for a building?
2.Determine the normal and critical depth for a 4-m-wide rectangular channel with a discharge of 100 m3/sec. The cannel is made of concrete and the slope is 1.0 percent. Also determine the flow classification (critical, subcritical or supercritical) when the channel flows at a normal depth.
3.A cast brass rod 60mm in diameter and 150mm long is compressed axially by a uniformly distributed force of 200kN. Determine the increase in diameter caused by the applied force, E=85GPa; poisson's rato=.30
