Determine the upstream depth of flow in a subcritical transition from an upstream rectangular flume that is 49ft wide to a downstream trapezoidal channel with a width of 75ft and side slopes of 2:1. The transition bottom drops 1 ft from the upstream flume to the downstream trapezoidal channel. The flow rate is 12,600 cfs, and the depth in the downstream trapezoidal channel is 22ft. Use a head loss coefficient of 0.5.
Water is pumped 9 mi from a reservoir at elevation 100 ft to a second reservoir at elevation 210 ft. The pipeline connecting the reservoirs has a 54-in diameter. It is concrete and has an absolute roughness of 0.003.
The elastic ball bounces down a flight of rigid stairs. Determine the height h of the steps if all the trajectories between successive steps are identical. Use e=0.85 and the initial velocity 6 m/s.neglect friction.(teta=70 degrees)
determine the velocity of the 30 kg block A if two block are released from rest and the 20 kg block B moves 0.6 m up the incline. the coefficient of kinetic friction between both blocks and the inclined plane is 0.10
An important dimensionless parameter concerned with very high-speed flow is Mach Number, defined as V/c, where V is the speed of the object such as airplane or projectile, and c is the speed of sound in the fluid surrounding the object.
The depth to water in A is 210 ft, in B is300 ft, and C is 230 ft. Determine the direction of ground water flow through the triangle ABC and calculate the hydraulic gradient. If the aquifer hydraulic conductivity is 30 ft/day, estimate how far gro..
A separatist Droid Army bettlestation is damaged during an intense battle over Coruscant, and it begins to fall towards to planet with an acceleration of s' = -gR^2/s^2 where s is the bettlestation's distance from Coruscant's center
Consider the steady-flow energy equation applied to the given extrusion process. Since the die is horizontal then there will be no change in potential energy from inlet to outlet. Hence the potential energy terms can be neglected.
A ferryboat queuing lane holds 40 vehicles. If vehicles are processed (tolls collected) at a uniform deterministic rate of 5 vehicles per minute and processing begins when the lane reaches capacity
the jib crane is supported by a pin at c and a rod at ab if the load has a mass of 2Mg with its com located at g determine the horizontal and vertical components of the reaction at the pin c
a moisture content of 10.2 % and a specific gravity of solids of 2.65. Compute the unit weight, dry unit weight, degree of saturation, void ratio and porosity.
a car travelling at 60 mph in a construction area skids into a stack of concrete barriers. skid marks leading to the
A core sample of basalt, 4 inches long and 2 inches in diameter, was tested in unconfined compression. The basalt is known to have a modulus of elasticity = 9.1 x 106 psi.
