A diffuser discharges wastewater into a slow-moving river that has a mean velocity of 3 cm/sec. After initial mixing, the DO concentration in the river is 9.5mg/L and the temperature is 15ºC. If the ultimate BOD of the mixed river water is 30mg/L, the rate constant for BOD at 20ºC is 0.6d-1, the reaeration rate constant at 20ºC is 0.8d-1, and the removal of BOD by sedimentation can be neglected, estimate the minimum DO and the critical location in the river.
A stainless steel tube with an outside diameter of 65 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 180 MPa, determine the maximum load P that the member can support.
The siphon crown is 1.2m above the water surface elevation of the reservoir and a length of 10m away from the siphon entrance. If the siphon diameter is 30 cm, the friction factor is 0.2, and the head loss coefficients are 0.2 inlet and 0.1 exit,
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of water gage. Determine the smallest standard commercial pipe that will give the required performance.
the 100 kg crate is originally at rest on the smooth horizontal surface. If a 200 newton force, acting at an angle of 45 degrees, is applied to the crate for 10 seconds. Determine the final velocity of the crate.
What is the ratio of the magnitude of E2 to the magnitude of E1? You may neglect the effects of gravity on the proton.
A room has 10 cotton spinning looms. Once the looms are set up, they run automatically. The setup time is exponentially distributed, with mean 10 minutes. The machines run for an average of 40 minutes, also exponentially distributed.
A 0.20 kg stone attached to a 0.8 m long string is rotated in a horizontal plane. The string makes an angle of 25° with the horizontal. Determine the speed of the stone.
A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest. ... forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
The path of motion of a 7-lb particle in the horizontal plane is described in terms of polar coordinates as r= (3t+2) and theta=(0.2t^2-t) , where t is in seconds. Determine the magnitude of the unbalanced force acting on the particle when t=3s.
