A company needs two parts, A and B, for its product. It can either buy them from another company, or can make them in its own plant, or do both. The costs of each alternative and the in-house production rates are as follows:
The company must have at least 100 units of part A and 200 units of part B each week. There are 40h of production time per week and idle time on the machine costs $3.00/h. Furthermore, no more than 60 units of A can be made each week, and no more than 120 units of B can be made each week. Also, no more than 150 units of B can be bought per week. The company wants to determine an optimal plan which will minimize the total costs per week. Formulate this as a linear programming problem and solve. What is the optimal make or buy plan for the company?
Water is pumped at a rate of 1.57 cfs from one large open tank into another through a 6 in diameter cast iron pipe 400 ft long. The water level in the second tank is 160 ft above the level of the first tank and the discharge end of the pipe is sub..
Calculate the reversible work out of the two-stage turbine shown in Problem 4.86, assuming the ambient is at 25?C. Compare this to the actual work, which was found to be 18.08 MW.
Wastewater is discharged into an aquifer. This wastewater contains 0.1 ppm atrazine (a common herbicide). The MCL of atrazine is 5 ppb, the density is 1.19 g/mL and the solubility is 50 ppm. 500 ft away from the plant effluent there is a permeable..
A 1.5-lb ball that can slide on a horizontal frictionless surface is attached to a fixed point O by means of an elastic cord of constant k = 1 lb/in. and undeformed length 2 ft. The ball is placed at a point
Assume you are an observer standing at a point along a three-lane roadway. All vehicles in lane 1 are travelling at 30 mi/h, all vehicles in lane 2 are travelling at 45 mi/h, and all vehicles in lane 3 are travelling at 60 mi/h. There is also a const..
The Tupperware hydroelectric plant on the Blackstone River has four 36-in-diameter turbines, each providing 447 kW at 200 r/min and 205 ft3 /s for a head of 30 ft.
If the man is always seated in an upright position, determine the magitudes of the horizontal and vertical reactions of the chair on the man at the instant \theta = 45^\circ. At this instant he has a speed of 6 {\rm m/s}
A bug is crawling up the leg of a man on a train. The velocity of the bug relative to the man is 0.3 m/s k . The mas is waling from one side of a carriage to the other with a vlocity relative to the train of 1.2 m/s j.
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 prototype and model will both be in air, if the prototype has a velocity of 500 ft/s and a diameter of 30 ft, what should the velocity for the model be if the model diameter is 2 ft
At 100 km downwind (y=10m), what is the concentration of NOx in g/m^3. The wind speed at the top of the stack with a height of 100m is 6.5 m/s and an inversion layer of 750m Pressure air = 95kPa
A camera is packed in a box and surrounded by packing material. The box is dropped vertically onto a horizontal surface. The vertical velocity of the box at the time that it hits the surface is v= 5m/s.
