1. What are the different types of stakeholder concern that may arise in a large system? How can aspects support the implementation of each of these types of concern?
2. Summarize what is meant by tangling and scattering. Using examples, explain why tangling and scattering can cause problems when system requirements change.
Number 3 fuel oil (30 API) is transferred from a storage tank at 60 deg F to a feed tank in a power plant at a rate of 2000 bbl/day. Both tanks are open to the atmosphere and they are connected by a pipeline containing 1200 ft equivalent length of 1...
Compute all the stationary spot price equilibria, (x0 , x1, P , r , G, T), in which P = r = 1.
a volume 10 in. long 5in wide and 0.5 in. thick is to be removed by face milling cutter that is 3in. diameter and has 6
A closed system consisting of 1 lb of a gas undergoes a process during which the relation between pressure and volume is pV^n = constant. The process begins with p1=20 lbf/in^2, V1=10ft^3 and ends with p2=100 lbf/in^2.

Half a kilogram of nitrogen, initially at 350K and 200Kpa is compressed through a poly tropic process with pv^1.4= constant. If the final temperature is measured to be 400K, find the work in the process.
A counter-flow double pipe heat exchanger is heat water from 20 degrees Celsius to 80 degrees Celsius at the rate of 1.2 kg/s. The heating is to be accomplished by geothermal water available at 160 degrees Celsius at a mass flow rate of 2 kg/s.
