A pump conveys water from an open pond through a short length of pipe to a nozzle that shoots water into the air in the middle of a fountain. The pump adds 5 H.P. to the flow. What vertical force (direction and magnitude) does the water exert onto the fitting that comprises the nozzle (essentially a 6 inch pipe cap with a 1 inch circular hole drilled in the center)?
A confined auquifer with a porosity of 0.15 is 30 m thick. The potentiometric surface elevations at two observation wells 1000 m apart are 52.35 m and 56.90 m. If the horizontal hydraulic conductivity of the auquifer is 25 m/ day determine the flow r..
the water tempearture is 10 degree celusis. how fast must the paddle wheel rotate in that compartment to generate a G(velocity gradient) value 30 s-1
What would the aperture have to be if there were two fractures of equal aperture. For your calculations you can assume that the rock matrix that contains the fracture(s) has zero hydraulic conductivity.
The influent suspended solids concentration to a primary settling tank is 435mg/L. The average flow rate is 0.050m3/s. If the suspended solids removal efficiency is 60 percent, how many kilograms of suspended solids are removed
two solid rods AB and BC are welded together at B and loaded as shown. Knowing that d1=50mm and d2=30mm, find average normal stress at the midsection of rod AB and rod BC.
A boad initially stationary at water,fires a shell in i direction,The shell's air speed =822 m/s.The shell was in the gu8n for .16s, and the force exerted on the shell decrease linearly fromthe initial force to zero over the firing interval.
A quality of water within a piston-cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor. The vapor then expands adiabatically to a pressure of ..
For a temperature of 10 degree C, calculate the time needed for the following particles to settle 0.3m: a) a 20um mineral particle with a specific gravity of 2.1, and b) a 2 um organic particle with a specific gravity of 1.2
A tub of a washing machine is rotating at 50 rad/s when the power is turned off. If it takes 15s for the tub to come to rest, determine (a) the constant angular deceleration, and (b) the total number of revolutions the tub makes.
a whirlpool is modeled as the combination of a free and a forced vortex. the maximum velocity in the whirlpool is 10 m/s, and the radius at the juncture of the free and the forced vortex is 10m.
Determine the minimum distance from the diversion that a road sign should be located informing drivers of the temporary change on the highway. The letter height on the road sign is 5 inches.
Two factories are manufacturing and supplying a single type of good to four warehouses. The factories can produce a1, and a2 units of the good each month, and the warehouses need b1, b2, b3, and b4 units each month, The monthly total of goods availab..
