A 60m-long siphon spillway discharges water at a rate of 0.32 M^3/sec. 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, what is the elevation difference between siphon crown and downstream pool? What is the pressure at the crown in KN/m^2?
At a certain location along the span, a reinforce concrete beam section with d=14 in. and b=10 in. is subject to a design shear of Vu=50k. Using No.4 stirrups, compute the required stirrup spacing at the given location. assume F'c=3 ksi and Fy=40 ..
A model of a submarine, at 1:15 scale, is to be tested at 0.8 ft/s in a wind tunnel at standard at mospheric pressure, while the prototype will be operated in seawater. Both the air and water are at 10 C (50 F).
A total of 13,610 kg/h of air at 1 atm abs pressure and 15.6C is to be heated by passing over a bank of tubes in which steam at 100C is condensing. The tubes are 12.7mm OD, 0.61 m long, and arranged in-line in a square pattern with Sp=Sn= 19.05mm.
The tank has an inner diameter of 1.5 m and a wall thickness of 18 mm. If the pressure in the tank is p=1.20MPa, determine the force in the 16 bolts that are used to attach the cap to the tank. Also, specify the state of stress in the wall of the ..
The number of hours on each machine required to produce a product is given in the following table, along with the number of hours available per week on each type of machine. Assume that the company can sell everything it produces.
Lines of levels were run requiring n instrument setups. If the rod reading for each backsight and foresight has a standard deviation δ what is the standard deviation in each of the following level lines?
an equal-tangent sag vertical curve is designed with the PVC AT STation 109 + 00 and elevation 950 ft, the PVI at station 110 + 77 and elevation 947.34ft,and the low point at station 110 + 50 . Determine the design speed of the curve.
The beam is simply supported and spans 25 feet. The beam must be designed for a superimposed uniformly distributed dead load of 1 kip/ft, and a concentrated live load of 12 kips that acts 10 feet from one of the supports.
The outside and inside diameters of 75 mm and 63 mm, respectively. A strain gauge is placed on the outside of the hollow segment of the tube to measure normal strains in the longitudinal direction. assume E=73 GPa and Poissons ration v=0.33. strai..
the maximum degree of curvature can be at most 6.0 and the superelevation can be at most +6.0%. Design the ramp for the highest horizontal curve design speed given the constraints.
Design a logic circuit that, when enabled with an active-high signal named en, will detect four different ranges of values for a 5-bit input number.
Assuming uniformly decelerated motion, determine the velocity and acceleration of point C of the belt, (a) immediately before the power is turned off. (b) 9 s later.
