A wave train moving from South to North has wave height 0.9 m and period 8 s. The still water depth is constant at 13 m. If a solid vertical reflective wall is now placed irn the water running East to West, plot the water particle trajectories (i.e. displacement with time) at a location 15 m to the South of the wall and 2 m below the mean free surface. You may assume perfect reflection of the wave train from...
Ex. 4 A water treatment plant with a maximum daily flow of 3 m/s (1.5 times the average flow) is treating a surface water. The water is coagulated with alum and the alum floc was measured to have a settling velocity of 2.2 m/h at 10 °C. Design a horizontal-flow rectangular sedimentation system based on the maximum day flowrate. Include the number of basins, dimensions and criteria checks.
A ball at ground level is thrown straight up with a speed of 12 m/s. How long does it take the ball to reach the maximum height? 0.82 s 1.02 s 0.63s 1.22 s What is the maximum height reached by the ball? 5.10 m 3.26 m 7.34 m 1.96 m The vertical component of the acceleration of a projectile remains constant during the entire trajectory of the projectile. True False For a projectile launched horizontally, the horizontal component of...
A 4 m high noise barrier is to be installed at the side of a major road, and concern is raised about its stability in high winds. It is supported by concrete posts every 20 m, and the maximum base shear force that each post can withstand is 75 kN. Wind tunnel tests reveal that the maximum pressure coefficient, based on the mean wind velocity at the top of the barrier, on the windward face of the barrier is 1.5,...

A hotel elevator ascends 200 m
with a maximum speed of 5.0 m/s. Its acceleration and deceleration
both have a magnitude of 1.0 m/s2. How far does the
elevator move while accelerating to full speed from rest? how long
does it take to make the complete trip from bottom to top?
