A gravel-packed well with an effective diameter of 36 in is to be constructed in an aquifer with T = 2.6 x 104 gpd/ft and S = 2.3 x 10-5. The design flow of the well is 1000 gpm. Calculate the drawdown at the well (use r which is the distance from the pumping well = 18 in) with total withdrawals from storage after (a) 1 min, (b) 1 h, (c) 1 day, (d) 1 month, and (e) 1 yr of continuous pumping, at design capacity. Repeat the calculations for r = 1m and 100m. (conversions: 1m3/d/m = 80.517 g/d/ft, 1 in = 25.4 mm, 1 gpm = 5.45 m3/d)
A crane is used to lift a concrete pipe weighing 10kN into place. For precision positioning, the worker at C can apply up a 800N force to cable AC. Determine the largest distance d the concrete pipe may be moved.
Compare the reactor volume required to achieve 95% efficiency for Completely Mixed Flow Reactor (CMFR) and a Plug Flow Reactor (PFR) for the following conditions. steady-state, first-order reaction, flow rate = 14m3 / day.
A wheel has an initial clockwise angular velocity of 12 rad/s and a constant angular acceleration of 3 rad/s2. A) Determine the number of revolutions it must undergo to acquire a clockwise angular velocity of 15 rad/s.
A chemical mixing basin is to be designed to blend chlorine and treated wastewater. The basin flow is 700 gallons per minute and the basin dimensions are 5 feet by 5 feet by 5 feet water depth.
The undeformed length of the spring is l. Knowing that the collar is released from rest at x = and neglecting friction between the collar and the horizontal rod, determine the magnitude of the velocity of the collar as it passes through point C.
For a drainage area of 5,187mil^2 mean annual runoff is determined to be 3,708ft^3/s and the annual averge rainfall is 35.5 inches. Estimate the annual ET losses in inches for the area.
At the end of the 6 years, the oil company exercised its option and bought the vessel. The chemical company has a 34% incremental tax rate. Compute its after-tax rate of return on the vessel.
A horizontal curve is being designed around a pond with a tangent length of 1200 ft and central angle of 0.5211 radians. If the PI is at station 145 + 00, determine the station of PT.
A 24-in.-wide by 0.100-in.-thick by 140-in.-long steel sheet is to be formed into a hollow section by being bent through 360° and having the long edges welded (i.e., butt-welded) together. Assume a cross-sectional medial length of 24 in.
the reliability is to be 95%, the overall standard deviation is 0.4, the drainage coefficient is 0.9, delta PSI is 1.7 ( with TSI of 2.5), and the load transfer coefficient is 3.2. the modulus of subgrade reaction is 200 lb/in^3.
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.
Determine the height "h" on the wall to which the firefighter can project water from the hose...and the speed of the water at the nozzle is v= 55ft/s. The firefighter is holding the hose 3.5 ft from the ground and the wall is located 15ft from the..
