A large company in the communication and publishing industry has quantified the relationship between the price of one of itsproducts and the demand for this product as Price = 150- 0.01 x Demand for an annual printing of this particular product. The fixed costs per year (i.e., per printing) =$50,000 and the variable cost per unit =$40. What is the maximum profit that can be achieved if the maximum expected demand is 6,000 units per year? What is the unit price at this oint of optimal demand?
Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day. At a distance of 20 km downstream of the treatment plant, the Pine River has an ultimate CBOD of 10 mg/L.
The mayor proposes financing the museum with a lump-sum tax of $24 and then opening the museum free to the public. How many times would each person visit? Calculate the benefit each person would get from the musuem, measured as consumer surplus minus..
The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
How much oxygen (mg O2) is required to support the complete oxidation of 500 mg acetate (CH3COOH). How much carbon dioxide (CO2) will be produced
A car traveling over a hill at constant speed starts to lose contact with the ground at O. If the radius of curvature of the hill is 85 m, determine the speed of the car at O.
A circular swimming pool has a diameter of 18 m, the sides are 3 m high, and the depth of the water is 2.5 m. How much work (in Joules) is required to pump all of the water over the side
Two parcels of air are mixed. The given properties of the two parcels and the final mixed parcel are as follows: parcel (1): volume = 1 Liter, Temperature = 10 Celsius, pressure = 1 atm, relative humidity = 50%, parcel (2): volume 1 Liter, Tempera..
What is the salt usage for each regeneration if the system regenerated every 10 days? What size resin tanks (diameter, height) would be required for a duplex system with no redundancy?
calculate the total metabolic heat generated by a singing canary taking into account heat transfer by radiation, convection and exhaling air. The air temperature is 20`C, canary's body internal and surface temperature is 33`C
The bar AB has an axial rigidity of EA. The bar is rigidly attached at A while there is a gap at B. A load P acts at point C and has a large enough magnitude to close the gap at B.
The acceleration of a particle as it moves along a straight line isgiven by a = (2t-1)m/s2 where t is in seconds. If s =1mand v =2m/s when t =0 determine the particles velocity and positionwhen t = 6s. Also determine the total distance the particle t..
