Water is transported from a reservoir at higher elevation to another reservoir through a series of three pipes. The first pipe of 400mm diameter is 500 m long, the second pipe 600 m long, size 300mm, and the last pipe is 500m long of diameter 200mm. If the elevation difference between two reservoirs is 30m, calculate equivalent pipe size and flow in the pipe.
determine the tangential component of the acceleration of the sled a) just before it reaches B, b) just after it passes C.
A wave has a height of 1.5 m in water 5 m deep and a wave period of 6 s. Plot the horizontal component of velocity, the vertical component of acceleration, and the dynamic pressure at a point 2 m below the still water level versus time for a 6-s i..
Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day. At a distance of 20 km downstream of the treatment plant, the Pine River has an ultimate CBOD of 10 mg/L.
What are the velocities of both just before impact and just after impact. There is a distance of 5m between the vehicles prior to the winch being turned on.
An open top tank contains a layer of SAE 30 oil 0.5 m thick, a layer of water 0.7 m thick, and a layer of mercury 0.3 m thick. Calculate the pressure, and the piezometric head at the free surface, at both interfaces, and at the tank bottom.
A rectangular plate 5ft by 4ft is at an angle of 30 degrees with the horizontal, and the 5-ft side is horizontal. Find the magnitude of the force on one side of the plate and the depth of its center of pressure when the top edge is (a) at the wate..
A stockpile of gravel that has a water content of 6% is rained on so that its water content increases to 9%. Compute the difference in the weights of dry gravel in a 10 ton truckload taken from the pile before and after the rain.
If there are 50 vehicles on a 4000-ft highway lane and the average time headway between two adjacent vehicles is 2.2 seconds. A) Calculate traffic density in vehicle/mile (vpm) and average space headway in feet/vehicle (fpv).
In bridge widening projects, the method of stitching is normally employed for connecting existing deck to the new deck. What are the problems associated with this method in terms of shrinkage of concrete
Soda Ash and QuickLime, A lime-soda softening plant treats a flow of 150 MGD, and the water has 86mg/l Ca2+, 35 mg/L Mg2+, 299 mg/L HCO3- and 6mg/l CO2.
Due to an error, the length L shown was 1.795 m instead of 1.80 m, thus there is a gap of 0.5 cm, which makes it difficult to bolt the bar on the structure. The engineer suggests the bar is heated up by - Delta in order to close the gap.
A driver with his passenger vehicle is driving at 35 mph, when the traffic signal in front of him changes to yellow. He is 100 feet from the intersection when he applies the brakes after a 1-second reaction time.
