A town obtains its water supply from two wells, W1 and W2. The cost of securing water from each well is defined as follows:
CostW1 = 13 + 4Q1 + (Q1)2
CostW2 = 26 + 8Q2 + 4(Q2)2
Where Q1 and Q2 are the amount of water in million gallons per day (mgd) from each well.
The town needs a total of 2 mgd. The capacity of well 1 is 5 million gallons per day, and that of well 2 is 10 mgd. Using calculus (hint: calculus with substitution), determine the optimal amount of water that will be drawn from each well if the town wants to minimize total costs.
Water flows at 0.32 m^3/s through a 600-mm-diameter pipeline with a head loss of 0.0029 m/m. Find the value of the Hazen Williams coefficient.
The lever BCD is hinged at C and attached to a control rod at B. Determine the maximum force P that can be safely applied at D if the maximum allowable value of the reaction at C is 250 lb.
Assume that the service station must fill refill the tank with 4.00 m^3 of gasoline once a week.Draw a mass balance diagram and estimate the annual loss of gasoline vapor (in kg/y) for the splash fill method
A jet on an aircraft carrier is launched by a catapult. What are some of the parameters that would be taken into account to make sure the aircraft achives a specified speed at the end of the ship
Stormwater controls are typically designed by civil engineers. Stormwater is collected in pipes below the ground and routed to nearby surface water
The acceleration of a particle is defined by the relationship a=-kx^-2 ft/s^2, where x is in feet and k is a constant. At x(0)=0.1ft, v(0)=0 and at x(1)=1ft, v(1)=10ft/s. Find the velocity at x=5ft.
The point of dicharge is 5 m abovethe floor, and friction losses in the 50 mm pipe from the resevoirto the tower amount to 2.5 J/kg. At what height in the resevoirmust the water level be kept if the pump can deliver only 0.1kW
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
Each of the three partners realizes that in order for the firm to continue at the present rate of growth a realistic business continuation plan must be in place which would include a viable buy-sell agreement between the shareholders.
A 2500-lb car (CD = 0.35, Af = 25 ft^2, and ? = 0.002378 slugs/ft^3) has 14-inch-radius wheels, a drivetrain efficiency of 90%, an overall gear reduction ratio of 3.2 to 1
What percentage removal should be expected for each of the following particle settling velocities in an ideal sedimentation tank: 0.1 mm/s, 0.2 mm/s, 1 mm/s.
A reinforced concrete beam having the cross section shown is on a simple span of 28ft. It carries uniform service loads of 3.60 kips/ft live load and 2.20 kips/ft dead load. Check the adequacy of the beam with respect to the moment.
