A sewer pipe is to be laid at a slope of 1 in 1800 to carry a maximum discharge of 600 liters/s, when the depth of water is 75% of the vertical diameter. Find the diameter of the pipe. Use manning's formula and take n=0.025.
Two kg of oxygen at 40C are contained in a 2 m3 closed rigid tank. Assuming that oxygen behaves as an ideal gas under these conditions, what is the gas pressure in the tank in bar.
Two water reservoirs A and B are connected to each other through a 40 m long, 2 cm cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve.
Neon gas at 50 degrees C in a vertical cylinder of diameter 150 mm has a 6 kg frictionless piston mounted. The outside pressure is 98kPa and the neon volume is 4000cm^3. Find the mass of neon.
You have been asked to design a simultaneous traffic signal system for six intersections on a suburban arterial. The distances between consecutive intersections are:
The force F is acting on the boom ABC at C points in the direction of the unit vector 0.7071i-0.7071j and its magnitude is 10kN. The boom is supported by a ball and socket at A and cables BD and BE.
Plot the magnitude of the force exerted on the gate by the brace as a function of the angle of the gate, , for . Assume the weight of the gate is negligible.
A colonist spaceship is a cylinder 3000m long and has a radius of 300m. The ship is spinning so the colonists experience gravity on the 'barrel'. No one lives on the end.
A trapezoidal channel having bottom width of 8 m and side slopes of 1 : 1, carries a discharge of 80 m^3/s. Find the conjugate depth to an initial flow depth of 0.75 m before the jump. Also determine the energy loss in the hydraulic jump.
A constant head permability test is performed on a soil that is 2 cm X 2 cm square and 2.5 cm long. The head difference applied during the test is 18 cm, and 5 cm^3 is collected over a time of 100 sec.
Explain the process for establishing a centerline for a roadway for an existing road. Include a description of the types of property markers used as well as any problems a surveyor may encounter in this process in your explanation.
A cantilevered W12x136 (ASTM-A36) steel member beam is 18 ft in length. If a concentrated load of 12 kips is applied at a point 6.25 ft from the beam's free end, use the superposition technique to find:
(a) Determine the distance d to the point where he lands. (b)What are the magnitudes of his components of velocity parallel and perpendicular to the 45 degree surface just before he lands
