The hypothetical velocity distribution in a horizontal, rectangular open channel is V=0.3y (m/s), where V is the velocity at a distance y (m) from the bottom of the channel. If the vertical depth of flow is 2 m and the width of the channel is 4 m, what are the maximum velocity, discharge, and mean velocity?
The rigid bar abcd is supported by a pin at B and restrained by identical steel bars at C and D, each of area 250mm 2 . if the temperature is increased by 8 0 C, find out the force P that will cause the bar at c to be stress-free.
There are no interchanges in the vicinity of this freeway segment. If the peak-hour factor is .90 and all of the drivers are regular users, what is the level of the service of this compound-grade freeway segment?
a) The maximum flow rate that can be achieved without cavitation occurring in the piping system. b) The maximum elevation of the highest point of the piping system to avoid cavitation.
The tape is stretched over three equal spans. Calculate the tape corrections under the following conditions at field, temperature = 85ºF, pull = 18kg, E= 2.109 x 10 6 kg/cm 2
Assuming unit surface area, find the conductive heat loss through the furnace wall and the temperature at the interface of the fire clay and red brick.
Due to a street crossing a roadway, the elevation of the roadway at station 3 +413.760 must be at 129.388 m. Design the curve?
Compute the maximum acceptable tensile service load T that may act on a single angle L6x4x3/4 that is welded along only one leg to a gusset plate; thus, there are no holes. The service load is three times the dead load. Solve for a0 A36 steel.
The total flow then moves to a point W on the traction drive two metres off the ground, and travels through a nine millimetre diameter conduit. Ignoring all friction and minor losses, determine the pressures at points H and W.
A car travelling at 60 mph in a construction area skids into a stack of concrete barriers. Skid marks leading to the crash measures 150 ft .
The difference between the total and static pressure before a shock is 75 psi. What is the maximum static pressure that can exist at this point ahead of the shock? The gas is oxygen.
A sample of natural glacial till was taken from below the groundwater table. The water content was found to be 52%. Estimate the wet density, dry density, buoyant density, porosity and void ratio. Clearly state any necessary assumptions.
determine the angular acceleration of the spool and the acceleration of the trailer. The wheels have negligible mass and are free to rotate.
