A long trough is supported by a hinge along its lower edge and a series of horizontal cables attached to its upper edge. Determine the tension in each of the cables, at a time when the trough is full of water. Ther are 4 cables, each one is 20 inches apart. The radius of the trough is 24 inches. The specific weight of water is 62.4 lb/ft^3
A 200 m wide natural stream, whose cross-section can be approximated by a rectangular cross-section, contains a dischargeof 80 cumecs. If the specific energy of the flow is 1.5 timesthe minimum specific energy
The steel beam ABCD is simply supported at A (pin) and supported at B and D by steel cables each having a diameter of 12mm. A force of 20 kN is applied at point C. For steel, let E = 209 GPa.
Concept of CSTR, A lagoon is to be designed to accommodate an input flow of 0.10 m^3/s of nonconservative pollutant with concentration 30.0mg/L and reaction rate 0.20/day
If the resultant force is directed along the boom from point A towards O, determine the values of x and z for the coordinates of point C. Set F sub B equal to 1490 N and F sub C equal to 2320 N.
A chair weighing 150 rests on a level floor that is not frictionless. A man pushes on the chair with a force = 43.0 that is directed at an angle of 34.0 with the horizontal. Assume that the chair is stationary but is on the verge of sliding.
The drag force (Fd) acting on a spherical particle that falls very slowly though a viscous fluid is a function of a particle diameter, d, the particle velocity, V, and the fluid viscosity, u.
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 thick steel sheet of area 440cm3 is exposed to air near the ocean. After a one-year period it was found to experience a weight loss of 880g due to corrosion. To what rate of corrosion in mm/yr dose this correspond
ABC is a triangular tract of land. The 1.5 tract DEFG is to be subdivided. AE is 480ft and DC is 350 ft. Determine the lengths of DG and CB. (Note 1 acre= 43,560 f^2)
Water, at volume flow rate Q=20 L/s, is delivered by horizontal fire hose and nozzle assembly. The hose (L = 100m, D = 75 mm, and e/D = .004) is made up of five 20 m sections joined by couplings
A pickle producing plant produces and discharges a waste brine solution with a salinity of 13,000 mg/L NaCl at a rate of 0.14 MGD into a stream.
