Scenario 14.1 — Vidalia OnionsWhen Vidalia onions are ready, the entire 13 county (plus parts of seven other counties) area in Georgia where they are grown is devoted to the harvest, packaging and shipping of this delicacy. The Onion Shack currently purchases 120,000 bags of onions each year at a price of $100 per bag (a bag is ten pounds). Onion Shack has historically purchased in lots of 3000 bags. Transit time and capacity vary as indicated in the table (lead time is 2 days more than transit time). The safety inventory that Onion Shack requires is 30% of lead time demand and the holding cost for a bag is 15% of cost. Carrier Quantity Shipped (cwt) Quantity shipped (bags) Shipping cost ($/cwt) Transit time (days) Mashburn Rail 200+ 2000+ $2.10 5 Sylvia Express 100+ 1000+ $2.35 3 Anita Enterprises 250+ 2500+ $1.35 3 Smith Trucking 250+ 2500+ $1.00 3 Use Scenario 14.1 to determine the inventory holding cost of the Anita Enterprises option if the Onion Shack purchases…

Instruction: Show your solution. (Engineering Utilities 2) Problem: A compressor draws in 500 cubic feet per minute of air whose density is 0.079 pounds per cubic feet and discharges it with a density of 0.304 pounds per cubic feet. At the suction, pressure # 1 = 15 pounds per square inches and at the discharge, pressure # 2 = 80 pounds per square inches. The increase in internal energy is 33.8 Btu per pound of air, and the heat rejected from air by cooling is 13 Btu per pound of air. Determine the work done on the air in Btu per minute and in horsepower. (1Btu = 778.16 ft-lbf; 1hp = 42.4 Btu/min)

You are to spray an 80-acre field that will be planted to alfalfa with 32 oz/ac Roundup, 1.5 pints/ac of Treflan, and 17lbs AMS/100 gallon spray. If your sprayer is calibrated to apply 10GPA carrier volume and holds 800-gallons how much AMS do you need to add to your sprayer to condition your water, and how many gallons of Roundup and Treflan do you need to add to your sprayer so that you apply the proper rate?
