a confined aquifer with a transmissivity of 7.0x10^-3 m^2/s and a storativity of 5.0x10^-4 is pumped by two wells 35 m apart. One well is pumped at 7.6 L/s and the other at 15.2 L/s. Plot the drawdown after 4 hours as function of position along the line joining the two wells.
A 500 lb flywheel is shown. A 100 lb block is held by a light cable wrapped around the hub of the flywheel the radius of which is 2 ft. If the system is released from rest and the weight has a velocity of 11 ft/sec after 5 s
A water tank has a height of 120m, and its area of cross-section is 2000m. Water is released from the tank and the water level drops by 1 meter every minute. Find the rate of change in volume.
Determine the total crop water requirement including the leaching ratio of a corn crop with a ECt of 1.7mmhos cm-1 if the ECiw of the irrigation water and precipitation is 5 and 0 mmhos cm-1 respectively
The column is constructed from high-strength concrete and four A-36 steel reinforcing rods. If it is subjected to an axial force of 37.5 kN , determine the required diameter of each rod so that one-fourth of the load is carried by the concrete
A slurry containing 20 percent by weight of limestone (CaCO 3 ) is processes to separate pure dry limestone from water. If feed rate is 2000kg/h, how much CaCO 3 is produced per hour?
The power loss, p , in a journal bearing depends on length, L; diameter, D; clearance, c; and rotational speed, w. You also have to worry about lubricant viscosity, density, and pressure. Obtain the dimensionless groups that charactrize this probl..
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
Assume the settling tank behaves like an ideal sedimentation tank, what percentage of removal should be expected for particles with a settling velocity of 0.002 m/sec
A 2.45 m wide rectangular channel has a bed slope of 0.0004 and Manning's roughness coefficient n of 0.015. For a discharge of 2.83 m^3/s, determine the type of water surface profile for depths of 1.52 m, 0.61 m, 0.30 m.
For a metal and wood structure, how would the economies of construction be obtained (pertaining to the mean and standard deviation of a probability of failure graph)?
Force F with magnitude indicated acts at point o. determine the magnitudes of the components Faa and Fbb along directions a-a and b-b so that F=Faa+Fbb
An airport corridor is 30 ft wide. given a peak demand of 300 pedestrians per minute and an average walk speed of 3 ft/s, estimate the LOS at the corridor
