APPLICATIONS OF FIRST ORDER DIFFERENTIAL EQUATIONS Newton’s Law of Cooling and Joint Proportions   At 4:00pm, a thermometer reading of 28 deg C is taken outside where the ambient temperature is –11 deg C. At 4:05 pm, the thermometer reads 8 deg above zero. After a while, the thermometer is returned to the room maintained at 28 deg C. At 4:12pm, the thermometer reads 15 deg C. When was the thermometer returned to the room?

Please explain in plain English how some designers have compromised efficiency for safety.

You need to heat 800.0 mL of vegetable oil from 20 to 190.0°C using an ethanol burner. Assuming a perfect transfer of heat from the burner into the oil, what mass of ethanol would be required (Note - ethanol has a molar enthalpy of -1277 KJ/mol)? Assume your kitchen is at SATP, vegetable oil has a density of 0.920 g/mL and the specific heat capacity of vegetable oil is 2.000 J/g °C.

The activities, duration and cost under normal and crashed conditions for a network diagram are shown in the accompanying table.    1. Determine the normal duration of the project 2. Determine the normal cost of the project 3. Determine the critical path under normal conditions.

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…

Problem 2.3 The following problem can be solved using the generalized conservation and accounting principle to determine if a recycling plant is profitable annually. Operating information: ● ● The plant operates 9 hours each day, 5 days each week, and 48 weeks each year. The plant purchases 30 tons of aluminum (at a rate of $0.02/lb) during each operating week. The plant has 5 full-time employees who are paid $18 per hour. All employees work during all of the plant's operating hours. The plant produces 7 bales of recycled aluminum per day, which it sells for $950 per bale. [Note: 1 ton = 2000 lb] Answer the following questions: (c) In order to determine the plant's annual profitability, would one be interested in studying the instantaneous rate of change in "stuff" (i.e. rate form) or the total change in "stuff" over an interval (i.e. finite-time form)? (d) On a system diagram (hint: think dashed lines!), use labeled arrows to identify each individual input and output of "stuff". (e)…

Automobile repair shops typically recommend that their customers change their oil and oil filter every 3,000 miles. Your automobile user’s manual suggests changing your oil every 5,000–7,000 miles. If you drive your car 15,000 miles each year and an oil and filter change costs $30, how much money would you save each year if you had this service performed every 5,000 miles?

1.1 As a maintenance planner, you are assigned to a food processing plant that is struggling with frequent equipment breakdowns and inefficient use of maintenance resources. What responsibilities and functions would you undertake to address these challenges? (4) 1.2 At a large manufacturing plant, a conveyor belt system requires a scheduled preventive maintenance task to replace worn-out rollers and inspect the belt for potential issues. Indicate the possible four individuals that would be involved in this maintenance task and what role do they play in ensuring that the task is successfully executed? (4) 1.3 A chemical processing plant is preparing for a scheduled maintenance shutdown. During this time, multiple tasks will be performed, including replacing a heat exchanger and inspecting pressure valves. The maintenance team uses both maintenance work orders and work plans to organize and execute these tasks. How does a work order and a work plan contribute to the successful…
