The gas pressure inside a piston-cylinder device is initially balanced by atmospheric pressure. the initial pressure is 100 kpa and volume of the gas in the cylinder is 32 cm3. a spring attached to the outside of the piston exerts no force on the piston. the area of the piston is 0.0004 m2. heat transfer to the gas causes the piston to move upwards by a distance of 2 cm. the spring constant is 10 n/cm. (a) determine the final absolute pressure (kpa) of the gas. (b) calculate the final volume (cm3 ) of the gas. (c) show the expansion process on a p-v diag

1. the materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. she knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. she also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four (4) days.2. at what point should resin be reordered? a. 0 kilograms remainingb. 50 kilograms remainingc. 200 kilograms remainingd. 400 kilograms remaininge. 500 kilograms remaining3. if order size was 1,000 kilograms of resin, what would be the length of an order cycle? a. 0.05 daysb. 4 daysc. 16 daysd. 20 dayse. 50 days4. if the order size was 1,000 kilograms of resin, what would be the average inventory level? a. 50 kilogramsb. 200 kilogramsc. 500 kilogramsd. 800 kilogramse. 1,000 kilograms5. if the order size was 1,000 kilograms of resin, what would be the daily total inventory costs, excluding the cost of the resin? a. $5b. $10c. $20d. $25e. $40
