A section view of a dam shown and water is stored at an elevation of 6 m above the base. the water flows through the dam in a concreate opening 2m high and 3 m wide. there are no losses or friction. the channel remains constant at 3m wide for a long distance. downstream, you notice the water slows down dramatically and goes through an increase in elevation of 2 meters. find the following; Velocity and flowrate through the dam. The kinetic energy as teh water flows under the dam. this section is 2m x 3m. Determine the kinetic energy after the stream has slowed down, the final section is 4m high and 3m wide.
Think of a situation where CAD is a better choice then traditional drafting. Given multiple ways to input coordinates, is one way better than another? Are there situations where you ell use one method over and other?
If the bar is 90 degrees F. If the bar is cooled to 40 degrees F, what is the maximum normal stress in the bar and what is the maximum shear stress alpha = 13*10^-6 /degF, E = 10*10^3 ksi
A bridge has cylindrical piers 1 m in diameter and spaced 15 m apart. Downstream of the bridge where the flow disturbance from the piers is no longer present, the flow depth is 2.9 m and the mean velocity is 2.5 m/s.
Neglecting the effect of altitude of local gravitional acceleration, determine the vertical distance climbed. Assume an average air density of 1.18 kg/m^3.
a rectangular prism box which is floating on water has a length L =1200mm, breadth = 800mm, height = 500mm and mass of 52kg. when the box is loaded with the suspended hexagonal mass, its immersion is 300mm, and when it the mass is placed inside th..
What annual investment is required at 8% per year compounded annually to accumulate to $100,000 at the end of 20 years?
Compute the volume of a waste sludge with 96% water content containing 1000 lb of dry solids. If the moisture content is reduced to 92%, what is the sludge volume
When a theoretical cutting plane is passed through an axially loaded prismatic bar, perpendicular to the longitudinal axis of the bar, and one side is analyzed as a free-body diagram, there is a uniformly distributed force acting on the bar's cros..
Mark's refrigerator has just died. He can get a basic fridge or a more efficient fridge with an Energy Star designation. Mark wants to consider a 10 year planning horizon using an interest rate of 5%.
The thermal efficiency of an aircraft gas turbine engine (turbojet, based on ideal Brayton cycle) is 25%. The aircraft travels at a speed 770 km/h at an altitude 6800 m above sea level (standard atmospheric air). The combustion chamber outlet temp..
A horizontal pre-stressing force of 750kn is applied to a rectangular concrete beam to be used as a structural member of a traffic bridge. The beam has a depth of 500mm and a width of 250mm. The force is applied at a distance of 80mm below the sec..
